Step 1: Cook some pasta...
Fill up a pot with water, put it on the stove, and wait for the water to boil.
Pick your pasta. I used Whole Grain Rotini, but really any shaped pasta will work. I personally like the rotini since the sauce gets all stuck in the curls of the pasta. Pour your pasta into the boiling water, add a bit of salt, and stir. You should turn down the heat a little at this point as well.
I like the directions on some boxes of imported Italian pasta that read "Cook until done." How much simpler could you get when telling someone how to cook pasta? How do you know when pasta is done? You taste it, of course! If it's not too chewy, drain the excess water out of the pot and set the pasta aside.
Step 2: Chop an Onion
It can't hurt to add more vegetables to the pasta. On different occasions, I've made this in the past with adding fresh spinach, basil, parsley, and bell peppers as well as the onion.
