• Preheat oven to 375℉.
• Cook pasta in salted boiling water until al dente. Set drained pasta aside until ready to assemble dish.

Italian Sausage: need pan with a lid

• Heat ½ tablespoon oil in a pan.
• Place sausages in the pan and sear both sides (2-3 minutes per side).
• Pour ¼ cup water into the pan, QUICKLY cover with the lid and turn heat down to low. Cook for 6-8 minutes.
• Remove sausages and let sit. Once cooled, cut into slices.

Sauce

• Heat 2 tablespoons oil in a pot.
• Add ½ cup chopped onions and sauté for about 3 minutes. Add 3 minced garlic cloves, crushed red pepper flake, oregano, salt and pepper and sautéed for about another minute.
• Stir in crushed tomatoes. Allow a low bubble to form for about a minute then stir in basil and bring heat down to a simmer until ready to use.

Vegetables

• Heat ½ tablespoon in a pan.
• Sautee ½ cup chopped onion for about 3 minutes. Add 1 minced garlic clove and sauté for about 30 more seconds. Add red peppers and zucchini and cook for about 4-5 minutes. Lastly, add in the spinach, once it begins to wilt, remove from heat. You don't want to over cook the veggies. They'll continue to cook in the oven and we still want a little crunch when eating.
• Remove pan from heat and mix in the sausage slices.

Assembly

• In a greased 9x13 baking pan, layer in half the noodles, then half the vegetables and sausage mix, then half the sauce, and sprinkle on half the cheese. Repeat this step with the other half of the ingredients.
• Bake uncovered in the oven for 30-35 minutes.
