I eat on around $120 a month. I buy mostly white rice, brown rice, potatoes, dried lentils, dried black beans, oats, bananas, mandarins, carrots, celery, onions, frozen broccoli, frozen soy beans, raisins, avocados, cucumbers, ground flax, dry roasted peanuts, almond milk, sauces, etc. I typically get some mixture of these or maybe some other goods if they are on sale. I like to buy in bulk. Largest container of everything. When in desperate times I literally survive on rice, broccoli, carrots, and lentils lol.
When I splurge it's on spinach, strawberries, cherries, bok choy, pineapple, etc.
