Method:
- Boil a saucepan of water, enough to cook the pasta al dente. Stir once to separate.
- Remove from heat and drain pasta in a colander, running through cold water.
- In a non stick pan, saute sliced onions, celery, and garlic. Add grape tomatoes cut into halves, some baby spinach, salt and pepper.
- Add pasta to the pan and the homemade pesto (I used basil, garlic powder, olive oil, salt and pepper).
- Sprinkle grated parmesan and serve warm.
