Rice, beans, pasta, oats, eggs, nuts, chicken thighs, tomatoes, paprika, onions, potatoes, olive oil, etc. All quite cheap. Requires a bit of initial thought and planning, and maybe experimenting with ingredients. Carbs and fat are both cheap, and protein can be in the form of chicken and eggs. Vegetables are kinda expensive so I go with mostly broccoli, cabbage, and stuff from the Asian supermarket. As for groceries, things like hygiene and cleaning products bring up total "grocery" bill, but $5 a day is very possible if it's pure food expenditure. German groceries are quite cheap actually. When I visited, I bought a kg of sauerkraut for 1 euro and a liter of soy milk for 1.5.
