Heat a large skillet over medium heat. Add 1 tbsp olive oil and the entire package of sausage (with casings removed, if there are any). Cook roughly 10 minutes, crumbling the large pieces and tossing occasionally. Once the sausage is thoroughly cooked, remove it from the pan and set aside. Do not clean out the pan.

Add remaining 3 tbsp oil to the empty skillet. Reduce the heat to low-medium and add diced onion. Sauté 5 minutes until beginning to soften. Then add minced garlic, 1/2 tsp salt, and 1/2 tsp ground pepper and cook an additional 3 minutes.

Add chopped tomatoes and basil to the skillet. Stir until combined, then simmer for about 20 minutes over low-medium heat, stirring occasionally. If there are large tomato chunks try to smash them as it cooks.

Finally, add cooked sausage to the skillet and simmer for an additional 5 minutes. Be sure to taste and see if it needs additional salt or pepper.

Serve with rice or pasta, and maybe a big scattering of goat cheese on top. Enjoy!
