When it comes to making snacking healthy, I find it helpful to be as creative as possible. Doing it this way makes you more likely to eat your vegetables and fruits because although it is just diced and chopped, it looks fancy and everybody loves a fancy dish. One day I literally had 1 mango, 3 avocados, and 2 roma tomatoes and took a knife and spoon and went to work.
Step 1: Cut each avocado in half and remove the seed.
Step 2: Take a spoon and scrape between the skin and the avocado to remove the skin while still keeping the avocado in tact. Place each halve around the parameter of the plate.
Step 3: Dice the roma tomatoes and divide the peieces equally into each avocado.
Step 4: Cut the mango in half and cut the mango vertically in 5 strips without cutting through to the skin. Now, cut the mango horizantally in 6 strips without cutting through to the skin.
Step 5: Push the mango from the skin upwards so that the fruit of the mango flips and points outward. Place the mango in the middle of the avocados on the plate and snack up!
