Why I Love This Grilled Watermelon Steak

Inspired by Family and Fire-Grilled Summers

Growing up in North Carolina, grilling was part of every summer weekend, but it wasn’t until a visit to a local food truck that I first tasted grilled watermelon steak. It reminded me of summers spent in my grandparents’ garden in Naples, where fresh fruit was our favorite “side dish” for every meal. With a little heat, the sweetness deepened into something rich and smoky. I recreated it for my dad one evening—he called it “the steak of the future.” That moment of surprise and joy is what this recipe is all about.
