Halve and pit the avocados, scooping the flesh into a medium-sized bowl. Mash avocado coarsely, leaving small chunks for texture.
Fold in the mango, strawberries, and jicama, and stir to combine.
Add maple syrup a bit at a time, tasting as you go and adding more as needed for desired sweetness.
Stir in the lemon juice and salt, followed by the mint leaves.
Taste for seasoning and add maple syrup or additional lemon juice as needed to balance the flavors.
Serve with jicama "chips".
Notes
To make jicama chips:Slice the base of the jicama off and then cut in half lengthwise. Peel the skin off from the base. Cut each half into fourths, then slice into 1/4" pieces. Slice each piece diagonally to make triangular "chips."
