There are so many variations of pasta salad. Here's the way I make mine...
1 Box of pasta
1 packet of dry Italian dressing
1 bottle of Italian dressing
Optional: (anything goes)
chopped tri colored peppers
Start with your favorite pasta. I generally use spaghetti, but sometimes I use rotini for the color.
Prepare a full box of pasta. This will serve plenty or keep it in the fridge all week for leftovers.
Drain pasta and cool. Add one packet of dry italian dressing. Add chopped vegetables and/or cheeses. I switch it up every time I make it.
