Speaking of oatmeal, it's another breakfast staple on my grocery list. Oatmeal is by no means the most exciting breakfast, but it's one of the cheapest and most filling. For a step above the microwaveable packets, I opt for quick-cook steel-cut oats ($2 at Trader Joe's). These stove-top oats cook in about eight minutes, and the container lasts for weeks in my pantry.
