Peel & cut up the mango into small cubes. Dice up some red onion. Chop the cilantro. Mix with salt in a bowl and add the juice of about 2-3 lime wedges.
Get your grill/pan/etc hot.
Add cajun or jerk spice into the ground beef and then divide into 8oz (1/2 lb) portions (or you can use smaller 6oz portions). Flatten into patties that are about 1/2 inch larger than the buns.
Put a thumbprint in the middle of the patty so it doesn’t puff up when cooking.
Grill your burgers about 4min on the first side.
Flip burgers and immediately add cheese. Put the buns face down on the grill. Cook until you reach the correct temp (140F for medium), usually about 2 to 4 minutes.
Place burger on bun and top with mango salsa. Enjoy!
