Simple vegetable frittata

I am all about simple meals with little prep time. But I also want something that leans toward the healthy side. Read: I am tired of eating pasta. I know that's shocking for those who know me, but I need a little break in my life. 

Last week (or the week before, I lose track) I made this simple vegetable frittata. This recipe is great because it's simple, it's cheap and it's a great way to use up any leftover vegetables you have lying around. 

This is what I used:

8 eggs

2 tblsp butter

1 cup chopped bell pepper (one small bell pepper) 

1 small onion, diced 

2 garlic cloves

1 cup spinach

1 small roma tomato

1/2 cup shredded turkey

1/2 cup cheese

salt and pepper to taste

Preheat your oven to 350. 

I used my stainless steel frying pan. You're going to need something that is both oven safe and easy to use on the burner. I melted the butter and sautéed over a low heat my onions, garlic and peppers for about five minutes. 

Then I added in my spinach, tomato and turkey. In a bowl I whisked together my onions and cheese. Then I poured the eggs into my skillet over everything else. I gave it a quick stir and let it cook till the top started to bubble. 

Then I slid the entire pan into the oven for about 10 minutes, just until it was cooked all the way through.
