If you have a sourdough starter bubbling away on your counter, you already know how satisfying it is to take something simple and stretch it just a little further—to turn leftovers, odds and ends, or yesterday’s discard into something delicious. This homemade lunch is exactly that kind of project—easy, fun, and nourishing. The kind of meal you prep ahead, tuck in the cooler bag with an ice pack, and send out the door knowing everyone is going to be happy come lunchtime.

This is our take on a childhood favorite—a make-your-own mini pizza kit that feels fresh, wholesome, and entirely homemade. Instead of dry crackers or processed crusts, we’re using sourdough starter to make soft little flatbreads. They have that light tang, a little chew, and just enough structure to hold toppings without crumbling.

Sourdough brings two things to these mini pizzas: flavor and nutrition. The slow fermentation supports better digestion, and even if your starter has been sitting in the fridge for a few days, it still brings all the benefits of long-fermented grains. These little flatbreads make for a lunch that feels both simple and special—something you made with intention.

Can I Use Freshly Milled Flour?

If you like to bake with freshly milled flour, you can easily substitute some—or even all—of the flour in your flatbreads. Freshly milled grains add a depth of flavor that pairs beautifully with sourdough’s tang. Whole wheat, spelt, or einkorn all work well here. Flatbread is so flexible. The sourdough process softens the whole grains and makes them wonderfully tender.

How to Make the Sourdough Flatbreads

Ingredients (no measurements):

• Sourdough starter (fresh or discard)
• Flour (any combination of all-purpose or freshly milled grains)
• Drizzle of oil
• Pinch of salt

Directions:

1. Mix the Dough – In a medium bowl, combine your sourdough starter with flour, a drizzle of oil and a pinch of salt. Stir until it comes together, then turn the dough onto the counter and knead for 3–5 minutes, just until smooth and elastic.
2. Ferment – Cover the dough and let it rest at room temperature for 4–8 hours, until slightly puffy and airy. For a slower fermentation, refrigerate the dough overnight.
3. Divide and Rest – Once fermented, divide the dough into small pieces about the size of ping pong balls. Shape each piece into a smooth ball and let rest 15 minutes before rolling out. This helps the gluten relax so the dough rolls easily.
4. Roll Out – On a lightly floured surface, roll each ball into a 3–4 inch circle, about ¼ inch thick.
5. Cook on Cast Iron – Heat a cast iron skillet over medium heat. Once hot, place a flatbread in the pan and cook until bubbles form and the bottom develops light golden spots, about 1–2 minutes. Flip and cook the second side for another minute. The flatbreads should stay soft with a few toasted spots.
6. Cool and Store – Let the flatbreads cool completely before packing or stacking. They’ll stay tender and flexible—perfect for layering with sauce, cheese, and toppings later.

Ingredients Breakdown For the Pepperoni Pizza Kit

Sourdough Flatbreads
A soft, rollable dough made from starter, a bit of flour to strengthen it, a drizzle of oil, and a pinch of salt. Once cooked, they puff lightly and stay tender—perfect for layering with sauce and cheese.

Pepperoni
Choose one that tastes good cold!

Sauce
A spoonful of marinara ties everything together. Since this meal is assembled cold, a sauce with good flavor makes all the difference. We start with a can of crushed tomatoes and add some Italian spices, salt, and olive oil.

Cheese
Shredded mozzarella is classic—it’s mild, creamy, and easy to pack. Freshly shredded tastes best, but the pre-shredded kind will save you time on busy mornings.

Optional Add-Ins
Try sliced bell peppers, olives, or a shake of oregano. Changing up the toppings keeps things interesting and encourages a bit of creativity at lunchtime.

Packing Tips

• Use a small jar (These are perfect!) for the sauce, and small squares of parchment to divide the cheese and the pepperoni.
• Pack a spoon or small knife for spreading.
• Always include an ice pack to keep everything cool and fresh until lunchtime.
• If you’re looking for a container, this Stainless Steel Bento Box looks perfect, and even comes with a little jar for the sauce!

These pack beautifully for school, work, or a day out, and they’re easy to assemble ahead in batches. This recipe makes about 18 flatbreads which means you have plenty to pop in the freezer for next week! Prepping a few at once means you’ve got grab-and-go lunches ready for the week—one less thing to think about on busy mornings.

Sourdough has a way of grounding us in the kitchen. Even something as small as a packed lunch can carry that sense of care and connection—real food, made by hand, with the kind of flavors that remind you why homemade always feels better.
