Step 1

Grease the skillet with olive oil and sauté chopped onions on medium high heat till they get soft, about 2-3 minutes.

Step 2

Stir in chopped bell peppers, mushrooms and garlic and combine well. Cook till the veggies get a little soft, about 3-4 minutes.

Step 3

Add in beef and sausage. Crumble with a spatula and add a little salt as it cooks. Cook till the meat is brown in color with no more pink, about 5 minutes.

Step 4

Add in diced tomatoes along with tomato sauce and Italian herbs and combine well. Simmer on medium heat for 20 minutes, stirring occasionally.

Step 5

Cook macaroni according to the package instructions. You want it cooked al dente, as it continues cooking in the oven.

Step 6

Preheat oven to 350°F.

Step 7

Mix half of mixed grated cheese into the meat sauce. Stir in cooked macaroni and mix well.

Step 8

Sprinkle remaining grated cheese on top of the assembled casserole. Loosely cover with aluminum foil. Bake for 40-45 minutes in preheated oven.

Step 9

Remove from oven and rest for 5-8 minutes before serving it up.
