Make-Ahead Breakfast: Crustless Spinach Quiche Squares

Crustless Spinach Quiche Squares - Cheesy, delicious and an easy way to have a tasty breakfast, lunch, or even dinner!We love make-ahead breakfast ideas, and these cheesy spinach quiche squares fit the bill. Adding spinach to your smoothie or eggs are some of the easiest (and tastiest) ways to get your greens in at breakfast.

And somehow, squares are always an easier sell than actual quiche when it comes to picky kids. If your family eats meat, a little bacon might also add to the kid-appeal.

If you’re all veggies, you can vary this recipe by adding sautéed chopped and seeded tomatoes or mushrooms. Feel free to get creative and swap the cheese in these spinach quiche squares for one with a more unique flavor like Gruyere, Jalapeno Cheddar or Dill Havarti.

Refrigerate any leftovers and reheat them the next morning. The Green Child team likes to save a square to make sure their workday lunch is protein- and nutrient-heavy.
