Just make whatever sauce you like and throw it on top and BAM spaghetti!
•For the pesto, just throw in a food processor a ton of basil, some olive oil, pine nuts (or walnuts because pine nuts are ridiculously expensive!) garlic, and salt and pepper. Just taste and add more of anything till it fits how you like it to taste.
• Chicken- just cut up about 2 breasts into pieces and toss them into a pan with some olive oil and garlic.
• When chicken is almost done, add chopped mushrooms and the pesto you just made. Add cut up cherry tomatoes a minute or so before serving.
• Zucchini – just slice it up with your peeler and add to hot water for about 5 minutes. Strain and serve with the pesto chicken mixture on top.
