This is a deliciously decadent, filling, and easily vegan pasta salad that I made up on the spot to bring to a potluck. It's so versatile, you can add or omit almost anything!
This is the perfect comfort food for cold days. To make it vegan, substitute non-dairy ingredients for dairy. Leftover filling makes a great lunch! If you want to make mashed potatoes from scratch, you will want at least 4 cups when you are through.
