0 Preheat the oven to 400F (200C).
1 In a large bowl, crack the eggs. Add the ricotta cheese, pinch of salt, cheddar cheese and onion. Mix well.
2 Add the flour, and baking powder, and mix well.
3 Line a 9x13 baking dish with parchment paper and pour in the egg mixture.
4 Spread the mixture out evenly with a spatula or the back of a spoon and bake for 20-30 minutes or until set (the eggs should not jiggle). A skewer/fork/toothpick should come out clean once inserted.
5 Let cool for 5 to 10 minutes, slice, and enjoy!
