How to Make It
Preheat a lightly oiled grill pan over medium-high heat. Sprinkle steak with salt and pepper; grill with onion, turning onion after about 4 minutes and steak after 7 minutes, until meat is medium-rare or to desired degree of doneness. Transfer meat and onion to a cutting board; let rest 5 minutes before slicing steak.
In a small bowl, combine honey, lime, olive oil, smoked paprika, and crushed red pepper; stir with a whisk. Set dressing aside.
Slice steak; arrange on platter with cantaloupe, onions, cilantro, and mint; drizzle with dressing.
