Give at-their-peak summer tomatoes a Tex-Mex spin with this simple, melty topping.
Position rack in upper third of oven; preheat broiler to high. Line a baking sheet with foil.
Combine cheese and jalapeños in a small bowl. Place tomato halves, cut-side up, on the prepared pan and sprinkle with salt. Top with the cheese mixture. Broil the tomatoes until the cheese is melted and lightly browned, 2 to 3 minutes. Garnish with cilantro, if desired.
