Buy the fukkk out of fruits and freeze ‘em. Bananas, blue berries, strawberries, etc. they hold up decently and can be good for smoothies.

Home make a bunch of sauces and freeze ‘em. Homemade chimichurri, carmalized onion, etc.

Grow your own greens, cucumbers, lettuce, green onion, etc. you got the space for a garden.
