Brown and drain the Italian sausage. Set aside.

Put the chicken broth, diced potatoes, minced onion, black pepper, crushed red pepper, parsley, and minced garlic in a large stockpot. Bring to a boil over medium heat. Reduce heat and simmer for about 15 minutes, until potatoes are tender, stirring occasionally.

Add the cooked sausage, half-n-half, cubed queso, drained corn, and diced tomatoes. Cook for about 5 minutes, until the cheese is melted and the chowder is heated through, stirring occasionally.
