A peanut butter and jelly sandwich made with 2 tablespoons of peanut butter on two slices of bread contains approximately 10 grams of protein. The amount of protein varies depending on the amount of peanut butter and the type of bread used to make the sandwich.
Two tablespoons is the recommended serving size of peanut butter and contains 7 grams of protein. Two slices of bread contain a smaller amount of protein, between 2 to 4 grams. A peanut butter and jelly sandwich provides 12 to 15 percent of the daily recommended protein allowance and 327 calories.
By contrast, a turkey sandwich with equivalent calories provides 20 grams of protein, or 40 percent of the daily recommended protein allowance.
