In a medium to large skillet, cook the ground sausage until fully cooked over medium high heat. Transfer to paper towel lined plate and set aside.Preheat your oven to 375°.
While the sausage is cooking, chop the broccoli florets off of the whole head. Likewise, chop the red pepper and slice the onion into thin pieces.
In the same skillet that you cooked the ground sausage, add the broccoli florets, chopped red pepper and sliced onion. Cook until the broccoli and red pepper are fork tender.
Once the vegetables are sauteed, crack 8 eggs into large glass bowl. Beat with a fork until thoroughly mixed.
Add sausage and vegetable mixture to the eggs before adding the Italian seasoning, salt and pepper.
Depending on how eggy you want your frittata to be, add in the remaining 4 eggs to the mixture one at a time, or until you reach your desired ratio. Make sure that there is enough egg mixture to thoroughly coat all of your vegetables and sausage.
Pour into a greased deep pie pan. If you do not have a pie pan deep enough, you can also use a cast iron skillet.
Cook for 40 to 50 minutes or until the entire frittata is well set.
Let sit for 10 minutes before serving. Serve plain or with salsa / tomato chutney over top. Enjoy!
