This vegetarian Slow Cooker Sausage and Peppers in Tomato Sauce couldn't be more comforting and is surprisingly healthy.

Whenever I am missing home, I immediately crave my grandmother's spaghetti sauce. We always had tubs of it frozen in the fridge and for someone who isn't a pasta person, I would gladly eat pasta every night if it was with her spaghetti sauce. And it was inevitable that her sauce always contained meatballs, sausages, or a combination of both. The past few weeks I have been thinking about her sauce and regretting the fact that I never learned to make it. Inspired by those memories, I set out to make an easy and meatless slow cooker recipe that would satisfy my sausage and spaghetti sauce cravings.

Since the sausage is a major player in this recipe, you want to make sure to choose a really good vegetarian Italian sausage. Personally my favorite is Field Roast. They have so much flavor and I like the texture better than lots of the other options out there. From there grab some crushed tomatoes, I always reach for San Marzano tomatoes if I can find them, garlic, peppers, and onions. Then wait for the slow cooker to work its magic and dinner is done.
