1Preheat your grill to medium-high heat.
In a small bowl, mix together the smoked paprika, cumin, salt, and black pepper.
Rub the spice mixture onto both sides of the sirloin steak.
Drizzle the olive oil over the steak and rub it in to coat evenly.
Place the steak on the preheated grill and cook for about 4-5 minutes per side, or until it reaches your desired level of doneness.
While the steak is grilling, warm the corn tortillas on the grill for about 30 seconds per side, or until they are slightly charred and pliable.
Remove the steak from the grill and let it rest for 5 minutes before slicing it thinly against the grain.
In a small saucepan, heat the pinto beans over medium heat until warmed through.
Assemble the tacos by placing a few slices of steak on each tortilla, followed by a spoonful of pinto beans.
Drizzle BBQ sauce over the steak and beans.
Top with diced red onions and chopped cilantro.
Squeeze fresh lime juice over the tacos before serving.
Serve immediately and enjoy your BBQ Steak Tacos with Pinto Beans!
