I tried the reflectix cozy / Grease Pot combo to cook up some whole wheat pasta while I was alone for the weekend (wouldn’t feed Julie that stuff, unless we were camping) and it did pretty well.

Boil 1.5 cups water, add 1 cup pasta, return to boil, put in cozy and cover. Wait 5 minutes and pasta is done, ready to drain and add cheese / sauce / etc.

For a full meal I’d use more pasta, but the smaller quantity is really the tougher test. Whole wheat pasta is weird but it cooks fast, and whole wheat really is better food.
