The best way to feed yourself if you are not at home in the kitchen is to keep it simple.
Today's example...
You need dip to bring to your poker game tomorrow, (try to make dips a day ahead, it helps the flavors burst) and you don't like the store bought junk.
Get a large container of sour cream, the real stuff, it's good for you.
Add 1/4 cup of grated parmesan cheese and one heaping teaspoon of Basil Pesto.
Stir up real good. You can put the sour cream in a big bowl to avoid slopping it all over the counter, and put back in container after it's mixed real well.
If you are watching carbs or calories use veggies not chips to dip OR rolled up ham/pepperoni/salami slices stab em with toothpicks to keep them rolled up. Chunks of cheese would be great also.
The next day everyone will think you are a Chef
