Get yourself a replicator like on startrek.
I’ve tried shopping, and don’t like how much stuff costs. It costs me more to buy the simple basics, especially milk and cheese here. The average block of cheese is almost 10 bucks here!
If I were working more, I’d keep a fridge stocked. As it is, it’s just not worth the hassle. I also find that I eat less just picking up something everyday, and eating just the one meal.
