Basic Marinara

Ingredients:
1 can of plum tomatoes
1 onion – thinly sliced into strips
1-2 bulbs of garlic – finely minced
(I prefer this sauce without the herbs but you can add ½ tsp of any dried - or a bunch of chopped fresh - herbs you like, like oregano; basil; thyme; tarragon; or Italian seasoning)
Salt and pepper to taste
(Add Spinach, or cooked chicken breast, ground beef, sausage, hot dogs, or whatever else you want to make it more like a meal).

Cooking instructions:
Fry the onions in a large saucepan until soft.
Add the plum tomatoes crushing them against the side of the saucepan with a wooden spoon, spatula, plastic spoon, whatever you're using to cook.
Add salt and pepper and herbs.
Stir occasionally until the tomato sauce bubbles.
Reduce to low heat and mix the minced garlic into the sauce.
Leave to simmer for 15 minutes or so.

You can eat this with pasta as it is, or use this sauce for almost any dish that requires a basic pasta sauce.
