First, preheat your grill or skillet to medium-high. Mix all the seasonings in a bowl and rub evenly over the steak. Cook each side for 3-5 minutes depending on thickness, then let it rest for a few minutes before slicing into strips.
While the steak rests, heat black beans and corn in separate saucepans over medium heat. Add a pinch of salt or extra spices if desired. I like keeping them warm but not mushy.
In a small bowl, combine sour cream or Greek yogurt with lime juice, zest, and a pinch of salt. Mix until smooth. This tangy topping adds a creamy, zesty kick to every bite.
Start with a lettuce base, then layer rice, beans, corn, diced onions, and shredded cheese around the bowl. Add sliced steak on top, then dollop with pico de gallo, lime crema, and guacamole. Sprinkle with cilantro and jalapeno slices if you like a little heat.
