So Simple, So Good.
Put the pasta water up to boil.
Chop an onion and start it sweating in a tad of olive oil.
Wash and chop a bunch of spinach.
Drop the pasta in the pot.
Throw the spinach in with the onions and cook until it wilts.
Remove the pasta from its pot to the pan with the spinach and onions, using a slotted spoon.
Stir in 1/2 - 1 cup ricotta cheese (use the purest you can find - read the ingredients - there should be only milk, vinegar, and salt).
Add a little pasta water to thin if you like.
Salt & Pepper to taste.
Top with a dollop of ricotta and little grated Parmesan if you like.
