Preheat oven to 425° F. Line a sheet pan with parchment paper.
Toss Brussels sprouts with olive oil and salt in a large bowl. Then transfer to the baking sheet with cut side down. Roast 15-20 minutes until brown and crispy on the edges.
Meanwhile, add sriracha, honey, garlic, lime juice and zest to a small saucepan. Heat over medium low, stirring often until thin and pourable. Remove from heat and let stand.
Pour the sriracha honey over the cooked Brussels sprouts once out of the oven and using tongs, toss well to coat. Serve immediately with extra lime wedges.
