Prepare pasta according to package directions.
While the pasta is cooking, bring a skillet to medium heat.
Add the olive oil and garlic and cook for 1 minute.
Add the crushed red pepper and onion powder and cook another minute, stirring throughout.
Drain pasta and add to the skillet. Toss to combine with seasoned oil.
Add tomatoes and fold into pasta. Stir while cooking 1 minute.
Add spinach and gently toss to combine as the spinach wilts for about 2 minutes.
TASTE! Adjust seasonings. Add salt & pepper to your liking.
Serve immediately! Top with fresh grated parmesan if that's your thing :)
