Prep the pan and oven: Heat the oven to 375°F (190°C). Grease a 12-cup muffin tin or line with parchment liners.
Make the crust: In a bowl, mix oats, almond flour, flaxseed, and salt.
Stir in olive oil and egg. Add water 1 tablespoon at a time until the mixture holds together when pressed.
Press the crusts: Divide the crust mix among muffin cups (about 1 heaping tablespoon each). Press firmly on the bottom and slightly up the sides.
Par-bake: Bake crusts for 7–8 minutes.
This helps them set so they don’t get soggy.
Prep the filling: In a large bowl, whisk eggs, cottage cheese, and Greek yogurt until smooth. Stir in shredded cheese, veggies, protein, mustard, garlic powder, onion powder, salt, and pepper.
Fill the pies: Divide the filling evenly into the warm crusts, almost to the top.
Bake: Return to the oven for 16–20 minutes, until the centers are set and the tops are lightly golden.
Cool and release: Let pies rest in the pan for 5 minutes. Run a small knife around the edges to lift them out.
Serve: Enjoy warm as is, or add a spoonful of salsa or hot sauce.
