A fair comparison starts with a fixed recipe. "Oatmeal" can mean a spoonful of instant flakes stirred into water, or a heaping bowl cooked in milk and topped with fruit, so every breakfast here is one specific build with gram weights. The builds are ordinary single servings, not calorie-matched portions. They range from about 126 calories for the yogurt bowl to about 575 for the burrito. Calories are listed for context but not scored.
The twelve builds
The two oat builds are identical on purpose. They let us isolate one variable, the cooking method, and see what it does to the clock.
Where the prices come from
Eight ingredients have a live national price. The Bureau of Labor Statistics publishes U.S. city average prices each month, and we used the August 2026 figures for grade A large eggs ($2.272 a dozen), low-fat and reduced-fat milk ($3.715 a gallon, about 23 cents a cup), bananas, strawberries, butter, cheddar and yogurt. Whole-wheat bread is the one exception. Its latest published month is May 2026 ($2.814 a pound), so that's the figure we used.
These are national price levels, not one store's shelf tag. The BLS average price fact sheet notes that some averages rest on far fewer price quotes than the index itself, so they carry some sampling wobble.
For everything else — oats, Cheerios, peanut butter, cottage cheese, frozen waffles, tortillas, frozen strawberries, salsa, refried beans and chia seeds — BLS has no average price at all. It stopped publishing a peanut butter price in December 2017. Those ten ingredients come from the USDA Economic Research Service's Purchase to Plate national average prices. That dataset prices thousands of foods per 100 edible grams from retail scanner data. Its latest vintage is 2017/18, so we moved each price forward to August 2026 with the Consumer Price Index series for its food group. Breakfast cereal prices, for example, are 27.2% above their 2017–18 average, and cheese products are 12.9% above theirs.
Two rules kept the price column honest. First, we used only rows the dataset prices directly from scanner data, and skipped the ones it imputes from a neighboring food. Second, the deflated prices are relative values carried forward, not shelf prices, and we say so here rather than hiding it in a footnote.
Those rules changed two builds. The dataset has no directly priced instant oatmeal packet, so microwave quick oats took that slot, priced from the same oats as the stovetop bowl. Every plain Greek yogurt row is imputed, so Greek yogurt is priced from the BLS yogurt series, which covers all yogurt. Greek yogurt usually sells for more, so the two yogurt-based rows are best read as a low estimate of their cost.
Where the minutes come from
Every build gets two times. Attended minutes are the minutes you have to be there: measuring, stirring, watching a pan, peeling, plating. Elapsed minutes run from the first step to the first bite. Toaster cycles, microwave runs and fridge time count as elapsed but not attended. Washing up is left out of every build.
The times are our estimates, built from published directions rather than a stopwatch. The oat times follow Quaker's own cooking directions. Old-fashioned oats simmer about 5 minutes on the stove after the liquid boils, and quick oats microwave for 1½ to 2 minutes. The egg, burrito, waffle and overnight-oats times come from extension-service recipes and package directions, cited in the sections below.
For another worksheet built the same way, with every price and gram shown, our batch-cooked chicken comparison runs the numbers on a different kitchen decision.

The three scores
Each breakfast is scored three ways: protein per attended minute, protein per dollar and fiber per dollar. The cutoff is 10 attended minutes or fewer. We name the best build inside that line, plus the best value overall. None of the scores is a health ranking. They measure what your time and money buy, nothing more.
