Favorite convenience foods

I live in FL and it is hurricane season. The other night, we lost power randomly in an evening shower. Just as I was preparing to cook supper. My daughter has a level 4 corn allergy. In that moment I panicked. It was bread baking day all my sourdough was proofing. We are an ingredient house obviously with her serve corn allergy. Everything has to be cooked. I ended up serving her a yogurt bowl with homemade yogurt, berries and homemade granola for supper. It got me thinking, with hurricane season and general preparedness. I have no convenience foods for her. Does anyone have any suggestions for power outage meals that are toddler friendly ? I feel like PB&J’s would be our best bet and I’ll be making bread more than one day a week to stay prepared.
