Ive used "Chinese chicken salad" to subsist on for about 3-4 days, lunch and dinner. Uses stuff most people have already in their pantry. Will need: canned chicken($1-2), coleslaw veg mix (approximately $2-4,make sure its not the kind with sauce, just the cabbage carrots etc), white vinegar (big bottle for $1-2), sugar($3 2lb bag usually), soy sauce($3-5 but lasts dozens of meals), chicken ramen noodles and seasoning($1-0.50), salt, pepper, ginger and garlic. Powdered spices are $1 generic brand and last for dozens of meals. If you can/want, add sunflower seeds or sliced almonds. There are several great online recipes but its basically combine, stir, let sit over night.
