Preheat oven to 375 F. Line deep pie dish or 8x11 baking dish with parchment paper or spray very well with cooking spray. Place 3 tortillas in a pie dish, overlapping each other and forming tall edges.
Crack the eggs, add cottage cheese and small dollops of pesto and sprinkle with salt and pepper. Whisk with a fork.
Top evenly with bell pepper, onion and cheese. Give a few stirs to combine.
Bake for 50-60 minutes or until the middle is set, check by inserting a knife until it comes out clean. If there is a bit of the liquid on top, it will solidify as quiche is cooling down.
Remove from the oven and let cool down for 30 minutes. Then cut with a knife and enjoy!
