I look at the things that make my life good:
Coffee: Love my Nespresso Love my Whole Earth natural sweetner, love milk in my coffee. Easy to stock up on the Nespresso & sweetner. Just started using Oat Milk ( yummy) and I realized the 2 quart container I bought at Trader Joes has an outdate of MAY 19, 2020. So next week I'll stock up on a couple of those and canned milk. I also have instant milk packets in my Earthquake Preparedness kit.
Oatmeal: Re-stocking my supply of pre-cooked Steel Cut oats. Have dried fruit to add if the quarantine means no more fresh blueberries *sad*
Backpacker meals: I find them to be tasty and easy. Also have a very long update and tend to have less sodium than canned foods. And the deserts are very yummy.
Extra stock of cleaning supplies as I assume cleaning will be a big part of keeping busy in a quarantine: Clothes detergent, dish detergent, dishwasher detergent, Mr. Clean Lemon (covers the ammonia smell very well), also lots of paper towels, added plastic bags, both kitchen and garden size.
Buying more bottled water. You never know if this stuff is gonna be found in water supplies !
