Spinach and Feta Frittata

My first attempt at a 'frittata' was a success. So much healthier than the usual Sunday morning breakfasts we have! 
Ingredients:
1/2 onion, diced
1/2 red and green pepper, diced
1/2 c chicken broth (can use veggie broth)
6 eggs
1 1/2 c milk
2 oz goat cheese, crumbled
1/2 package frozen spinach (thawed, drained well)
salt
pepper
garlic powder
parm cheese

Directions:
Sautée some onions and peppers in chicken broth (just to soften).  Mix with eggs, milk, goat cheese and frozen spinach (drained well), salt, pepper and garlic powder. Sprinkle with a little parm cheese. Cook at 350. For about 30 mins or until the eggs looks cooked and fluffy.
