As far as actual food goes:
You can do better, and you can do worse.
MREs are useful if you need multi-year shelf stable food that comes with an assortment of stuff (drink mixes, condiments, utensils).
Regular food - even frozen TV dinners - may be less expensive, are certainly more easily available, and probably come in a greater variety.
I suggest getting some canned soup, too - just to break the monotony.
