• 1 small red onion, cut through root end into 8 wedges
• 2 teaspoons vegetable oil

• 2 medium beefsteak tomatoes, chopped
• 5 Fresno or other medium-spicy chiles, 3 with seeds removed, chopped, 2 thinly sliced

Steps

1. Prepare a grill for medium-high or heat broiler. Toss onion with oil in a medium bowl; season with salt. Grill or broil, turning occasionally, until blistered on all sides, 8–10 minutes. Let cool, then chop.
2. Toss charred onion, tomatoes, both types of chiles, and lime juice in a clean medium bowl to combine. Let sit, tasting every few minutes, until desired level of heat is reached, then discard habanero; season with salt.
3. Do Ahead: Salsa can be made 3 days ahead. Cover and chill. Taste and adjust seasoning with more salt and lime juice just before serving.
