What are your go-to freezer or shelf stable meals when life catches you off guard?

I didn't want leftovers for lunch today so I stopped at the store on my way to work and bought a Lean Cuisine meal- here's the description for the "Salmon Mediterranean": wild salmon with zucchini, peppers and whole grain pasta in a garlic tomato sauce. I'm sure none of you will be surprised to know that is wasn't very good.

I brown-bag it 95% of the time so I only buy pre-packaged meals out of desperation, but I'd sure like to avoid a catastrophe like this again. Suggestions would be most appreciated!
