You're in Texas I realize that it can get cold (chilly) but not really that cold. I wouldn't think you need to be resorting to MREs and other kind of food stuffs especially if you have a generator that can run your refrigerator for the time the power is out. You should be able to eat largely a normal diet unless you realize solely on a microwave and frozen dinners for your food. A propane grill means that you should be able to cook nearly everything you would in a kitchen. A charcoal or Wood grill would work as well just cook outside it's not that cold. Through most of human history people cooked over fire.
