Store food you like to eat and learn to store it safely. Some ideas to keep in mind is it must be something you can cook/heat or eat cold. Using the 10 gallon tupperware bins are great for storing whatever foods you pick for storage. If you like peanut butter and jelly get some. Crackers can take the place of bread an extra box should not break your budget. Quite a lot of fruits, veggies and eggs can be stored outside the fridge. Some deli meats and jerky are shelf stable and add variety to your meals.
Canned soups and veggies along with pasta rice and sauces can be easy to boil or heat and eat. Add some tang, coffee, tea, bullion and using just the little Sterno stoves you can have something warm to drink and warm food to eat with very little work. Spices and herbs for seasoning can change a simple little meal as well as adding in a few vitamins you can stay healthy and keep your immune system as strong as possible.
Or you can have a camp cooler full of shelf stable food you like and in an emergency it can be a backup if you get ice. If the power is going to be out for more than a day you start eating the food out of your refrigerator but keep it shut as much as possible so it stays cold. If it’s under 40 Degrees F. you can store your food outside. Next got to work eating the food in your freezer and if it is below 20 degrees F. you can have your frozen goods outside and add a few water bottles outside to freeze over night that can stretch how long your food stays cold and frozen. If you can run a generator safely only run it 2 hours twice a day for the fridge and freezer. That should keep everything cold and stretch your fuel supply.
Get a pressure cooker and learn to cook with it. It’s amazing how fast they cook. Dried Beans can be cooked in an hour instead of 4-5 hours. Now this way of cooking needs to be practiced but as far as saving time and energy the pressure cooker is a great addition to you kitchen and they cost a lot less than a pressure canner!
Some tools I recommend is a good quality can opener and 1 for backup. Tinfoil is cheap and can make a little pan and then throw it away to save water on cleanup. Have a couple of wash tubs for dishes and plates and use the water to flush your toilet. If trash pickup is slow, keep “construction grade” trash bags on hand, They are more expensive but hold a lot of trash and are very strong. The bags are a big help for when you are cleaning up after the storm. If you have to evacuate put the food from the fridge and freezer in the bags it will help doing the cleanup when you get back home if the power gets turned off.
You know yourself and your family much better than I do but I can tell you eating foods you like and are able to cook easily will help make you feel more in contol. This is a great time to buy those little fun size candy bars and have them stashed away or baked goods items for making breads, cakes and pies are on sale. Have those things on hand for a treat or morale booster. Heck graham crackers, a hershey bar and a marshmallow roasted over the canned heat stove might be a great treat at the end of the day.
