Take a large bunch of fresh basil, about an equal amount of baby spinach, 2 cloves of garlic, 1/2-1 teaspoon salt (depending upon taste) and 1/4 teaspoon pepper and chop in a food processor slowly adding olive oil until saucy. Then add some grated cheese and blend again. You can also add pine nuts if you like.
When you serve with the pasta, save a little of the past water and add it in with the sauce. This helps bind everything. That’s it. Really easy!
