Optional: 2 to 4 tablespoons fresh parmesan cheese
In a large pot, make pasta as directed on the box/bag of pasta you are using.
Drain pasta and set aside.
In the same pot, heat 1 tablespoon of oil and sauté garlic for 30 seconds. Add in broccoli and asparagus and sauté for 5 to 10 minutes until fork tender. To speed up the time, add 2 teaspoons of water and cover the pot.
Remove the casing from the sausage and add to the pot. Cook until no pink remains.
Add the spinach and sauté until wilted.
Add the pasta into the pot, add remaining olive oil, and salt, pepper, red pepper flakes, and parmesan if adding. Taste and adjust spices as desired.
