Hey there, I used the recipe calculator (new recipe) to add up your calories. A cup of whatever fruit is typically 20 chunks so using that and assuming your 3 slices was about a 1/3 of a whole orange calorie count says its only 62 calories... Here's what i put in just for reference: .2 cup watermelon .15 cup
cantaloupe 6 grapes 1/3 orange .1 cup honeydew Best of luck to you! ~Ashe
