Easy Vegan Mac and Cheese with Daiya

I threw this together a few nights ago and it was very easy and yummy. If you prefer lots of sauce with your pasta, either make more sauce or less pasta; it isn't super saucy in this incarnation.

Easy Vegan Mac and Cheese with Daiya

12 oz. pasta, cooked (I used whole wheat spirals)
2 tablespoons soy margarine
1 cup Daiya cheese shreds
1 cup plain soymilk (or other non-dairy milk)
1/2 - 1 teaspoon garlic powder
1/2 - 1 teaspoon salt
1/4 teaspoon pepper

While you're boiling the pasta, combine all remaining ingredients in a medium-sized pot over medium heat. Bring to a gentle boil and cook for a few minutes, stirring often. Pour sauce over cooked pasta and toss well.
