What is the average cost of a breakfast meal
(0) Comment |. A fast-food meal may sound like a good deal, especially when you donât have time to prepare breakfast or lunch. A comparison of cost vs. nutritional value, however, paints a very different picture. The average cost of a combo meal at a fast food restaurant is $4 to $7.Preparing a comparable meal at home costs about the same, but the real savings are in the calories, fat, and sodium. comparison of cost vs. nutritional value, however, paints a very different picture.
