On my last grocery trip I took my huge hiking backpack:
3 cartons of local extra-firm tofu
a huge carton of pre-washed mixed salad greens
fresh apples, tangerines and bananas
frozen peas
jar of peanut butter
bottle of agave syrup
a huge bag of pre-mixed muesli
2 large cartons of cashew yogurt
1 carton of coconut milk
2 packages of Field Roast vegan sausages
2 loaves of bread
1 jar Vegenaise
1 jar dill pickles (this and the Vegenaise were my two heavy glass jar "splurges")
a bag of Yerba Mate loose grounds
huge Asian bag of rice
4 pkg veg instant ramen
1 onion
Assorted lemons, limes and fresh ginger
Not Beef and Not Chkn bouillon
1 small container red pepper hummus
1 Miyokos Roadhouse cheddah
local vegan bakery chocolate chip cookies
vegan korean bbq "rinds" and vegan nacho chips
a normal 4-roll package of recycled toilet paper
1 over-the-counter painkiller/fever reducer
1 generic package benedryl-type antihistamine
2 bars hippie hand/body soap
1 container hippie laundry soap
Most of this was in light paper or plastic packaging, or no packaging at all, so I was able to hike a mile with my full backpack and a grocery bag in each hand, with rest stops. This was definitely over my normal hiking limit, but I made it home and rested up the next day. This was seven days ago, and I am still good for maybe another seven, since I already had previously stocked up on things like nuts, dried fruit, canned beans and canned soups, dried beans and lentils, oats, hot sauce, ketchup, mustard, salad dressings, multi-vitamins, shampoo, teas, and sundry dried goods that store well.
I probably could make it another two weeks or longer, realistically if I absolutely had to, if I were to eat nothing but beans and rice for a week of it. But I will want more fresh food by next week. I have considered ordering from Vegan Essentials so I don't have to go out, but they don't deliver produce. I refuse to order food someone else cooked, as I am even avoiding two of my own roommates due to their crazy extroverted ways. I am in super-lockdown. My reasoning is I won't get anyone else sick if I don't get sick, and if I am exposed to as few germs as possible, I will get less ill if I do. People with multiple, messy exposures are at greater risk for more severe complications. I managed cloth masks for myself, and managed to set up a mini-kitchen with a rice cooker and hot pot in my bedroom (which is large enough to be comfortable with this set-up). I had to do this, lest I start spraying Mrs. Myers cleaner in my roommates faces to keep them and their friends away from me.
