Cut the focaccia into 12 pieces by cutting a 3x4 grid, and then cut each piece horizontally. Cut the eggs into 12 pieces that match. Spread aioli on the top half of each sandwich, and to the bottom add egg soufflé with cheese and then bacon. Finish with the top piece of focaccia.
To serve immediately, cover the pan with foil and place in a 300-degree oven for 5-10 minutes until the sandwiches are warm through. Serve warm and watch them disappear!
To freeze and serve: Wrap each sandwich individually in foil and freeze. To reheat, place wrapped sandwiches in a 300-degree oven for 30-40 minutes, until warm through.
