"Alexa, ask food suggester to find me a food that has 220 calories"
"List some foods that have 450 calories"
"Please offer me a food that has 65 calories"
This skill allows you to find some unique options with a specified amount of calories, ask Alexa for a food with a certain amount of calories, and she will suggest foods with that amount of calories, or something very close to it! Once you get an idea from Alexa, try looking up a recipe and make the dish for yourself!
