Preheat oven to 375ºF and lightly grease an 8x8" casserole dish or 9" pie pan with olive oil.
Place corn tortillas on the bottom of the pan. You might need to cut the corn tortillas to fit the pan size.
In a small bowl, beat eggs and milk with a whisk.
Spread the refried beans on top of the corn tortillas. Evenly place the roasted red peppers on top of the refried beans. Place baby spinach on top of the roasted red peppers. Pour egg mixture on top and sprinkle with cheese. Bake for 30-35 minutes, until cooked and quiche is golden brown.
Top with salsa and cilantro, serve.
