Combine the diced mango, red onion, jalapeno, lime, honey and cilantro. Toss to combine.
Prepare the avocados by slicing them, removing and discarding the pit and peels then mashing them with a fork to the texture you enjoy. Season well with kosher salt and pepper, give a good squeeze of lime and mix until combined. Taste and adjust. If you like things spicy, add in a sprinkle of cayenne pepper.
Toast your bread or use the grill to warm it up. Assemble and enjoy!
