In an oven safe pot (such as a Le Creuset dutch oven) or skillet, add olive oil and heat to medium high heat. Add the sausage and onions and cook until brown and soft, about 5 minutes. Add the garlic and cook until fragrant, about 30 seconds.
1 tablespoon olive oil, 1 pound smoked sausage, 1/2 large onion, 2 cloves of garlic
Add the chicken broth, can of tomatoes and green chilies, heavy cream, pasta, salt, and pepper. Stir to combine and bring the mixture to a boil. Reduce heat to medium low heat, cover and let simmer until pasta is cooked through, about 12-15 minutes, depending on what type of pasta you're using.
2 cups low-sodium chicken broth, 10 ounce can of tomatoes and green chilies, 1/2 cup heavy cream, 10 ounce wagon wheel pasta, 1/2 teaspoon salt, 1/2 teaspoon black pepper
Remove pot/skillet from heat and add 1/2 cup of cheese. Stir to combine then top with the remaining 1/2 cup of cheese. Broil in the oven until the top of the cheese is melted and bubbly.
1 cup Monterey Jack cheese
Serve immediately and garnish with scallions. Store in an airtight container in the refrigerator for up to 5 days.
