Pasta with Sausage, Peppers and Spinach

This is a spicy, flavorful, pasta dish wish sausage, red pepper, and spinach. I started off making this recipe, and changed things to more my tastes. It came together pretty quick. I love skillet pasta meals!

Pasta with Sausage, Peppers and Spinach

Ingredients:
Olive oil (for the pan)
1 pound hot (or sweet) Italian turkey sausages (if you like to remove the casings, like I do, you won't need olive oil for the pan)
1 red bell pepper, diced
1 onion, diced
1 tsp salt
1 tsp pepper
4 garlic cloves, minced
1/2 tsp oregano
2 Tbsp basil
1 8 oz can of tomato sauce
1/2 cup Marsala wine
1 14.5 oz can of diced tomatoes
A few big handfuls of fresh spinach, cut
1/4–1 tsp crushed red pepper flakes (optional)
1 box of pasta (I used spiral and penne—that's what I had)
Freshly grated parmesan cheese, for garnish

Directions:
Heat olive oil in a large skillet over medium heat. Add the sausages and cook until browned, about 7–10 minutes. Remove sausage from the pan and place onto plate covered with paper towels to absorb grease. Keeping the heat on medium, add peppers, onions, salt and pepper, and cook until golden, about 5 minutes. Add the garlic, oregano and basil and cook for two minutes. Add the Marsala wine, tomatoes, tomato sauce, and crushed red pepper flakes, if using. Stir to combine, scraping the bottom of the pan with a wooden spoon to release all the brown bits. Bring to a simmer.
Return the sausage to the pan. Simmer uncovered until the sauce has thickened, about 20 minutes. Add the spinach and saute for a couple minutes, until it is wilted. *Note: I only let it simmer about 7–10 minutes. So if you do this, cook the pasta while you make the sauce.
