Stock up on canned tuna (and/or a whole chicken roasted), eggs, dried beans and rice, and cost-effective fresh and frozen veg&fruit.
-Rolled oats with frozen berries and peanut butter, and an egg for breakfast
-Salad and tuna/chicken, with a piece of fruit for lunch
-Beans, rice, and 2-3 veg for supper (chicken broth from the carcass is great for cooking rice)
Vary sauces/seasonings accordingly, and there's your meal plan.
