Heat olive oil in a large skillet on medium-high. Add one piece of onion – when you hear it sizzle, it’s time to add the peppers and onions. Start the water for pasta.

When the peppers start to soften and the onions are beginning to brown, add the sausage, garlic, salt, pepper and Italian seasoning. Using a wooden spoon or spatula break up the sausage and continue to stir until it is cooked through and browned.

Create space in the center of the ingredients and add the butter. When butter is melted, add baby spinach and stir with the rest of the ingredients.

Water should be boiling by now, so add the pasta!

Once the spinach is sauteed and stirred into the sausage mixture, bring heat to low and stir in sauce. Cover and stir occasionally until pasta is done.

Remove skillet from heat. Drain pasta and stir into sausage mixture.

Sprinkle a little shredded mozzarella, parmesan or provolone to be fancy!
