Steak Tacos With Grilled Pineapple Salsa

Preheat grill to high. Stack tortillas and wrap in heavy-duty foil. Combine oil, 1 teaspoon chipotle powder, and 1/2 teaspoon salt in a small dish. Rub mixture into both sides of steak. Place the tortilla stack on the coolest part of the grill or upper warming rack, if possible, and heat, flipping once, until warmed through and very pliable.

Meanwhile, grill the steak for 4 to 6 minutes per side for medium, or until desired doneness. Grill pineapple rings until moderately charred, 1 to 2 minutes per side. Remove the tortillas, steak, and pineapple from the grill. Let the steak rest for at least 5 minutes before slicing very thinly crosswise into strips.

Meanwhile, dice the pineapple and transfer to a medium bowl. Add bell pepper, onion, cilantro, vinegar, the remaining pinch of chipotle powder, and the remaining 1/2 teaspoon salt; toss to combine. Serve the sliced steak in the warm tortillas with the pineapple salsa.
