You know one of the best things to do with your leftover vegetables?

Make a frittata!

I always want to call it a quiche but since I never make it with a crust, I guess I must call it a frittata. Or “crustless quiche” has the same number of syllables.

Anyway, as long as you have a few eggs on hand and spices, it’s super easy to use up your vegetables with this dish.

This time the vegetables I had on hand just so happened to be zucchini, bell peppers and spinach.

The secret is to saute the vegetables with herbs before baking! That makes them tender and evenly seasoned.

Add the spinach afterwards because it cooks down so quickly, but be careful it doesn’t spill out the sides.

Use a spatula to kind of push it down into the other veggies and it’ll cook down in a minute or two.

Then it’s time to add eggs + milk!

You can whip them together in a small bowl first if you’d like, or skip that step and just plop the eggs and milk right on top and then use a fork to whisk into the vegetables.

It all seems to mix in the same.

Baking on the stovetop for a few minutes seems to help the middle cook evenly, so I like to do that before putting it in the oven.

Top with some tomatoes…

…and cheese, if you like.

PRO TIP: At the end of baking, turn on the broiler on ‘high’ for 2-3 minutes to brown the cheese and pop the tomatoes.

Delicious. I doubled the recipe and doubled the cook time. I used cheddar cheese because that is what I had available and it complemented the dish well. This recipe is a keeper!
