Gather all your ingredients. Chop the bell peppers into strips, dice the onion finely, and mince a few cloves of garlic.

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the Bob Evans Italian sausage and cook for 5-7 minutes until browned and cooked through.

Once the sausage is fully cooked, add the chopped onions, bell peppers, and minced garlic. Sauté for an additional 5-10 minutes.

Stir in the canned diced tomatoes, along with the Italian seasoning, salt, pepper, and red pepper flakes. Simmer for another 5-7 minutes.

Taste the mixture and adjust the seasoning if necessary. Serve hot, with optional garnishes like fresh basil or grated cheese.
