Those ER bars are pretty horrible for you if you're not starving to death. Ingredients: Flour, Vegetable Shortening, Sugar, Corn Syrup.
Cheapest Protein: Whole Eggs, Chunk Light Tuna, Egg Whites, Skim Milk, Whey Powder. That's it for the decent tasting and healthy stuff (low in saturated fat). I'm sure you can find fatty beef, chicken gizards & hearts, etc pretty cheap too. Protein in general though is much more expensive per calorie than carbs or fat.
Cheapest Carbs: The raw bulk stuff is the cheapest by far. Rice, Dried Beans (kidney, black, etc), Lentils, Pasta, Oatmeal, etc. The problem with those is that you usually have to spend more for them to taste good (spices, sauce, broth, etc). And of course they take more time to prepare than other carb sources like bread and tortillas. Generic Mac N Cheese is actually pretty cheap. Plain sugar & dextrose are very cheap too but you obviously don't want to make them a huge part of your daily intake.
Cheapest Fats: Peanut Butter, Olive Oil (or other oil). Both very cheap. Probably the densest form of calories you'll find. 95-120 calories per tablespoon. The Extra Light Olive Oil is tasteless when added to other foods.
