Add 2 short ribs with their liquid to a skillet; heat over med-low 5-6 min, turning often, until warmed through; using two forks, pull meat into bite-size pieces + reserve hot sauce on the side

Meanwhile, stack 6 tortillas on a plate + wrap with a damp paper towel; microwave 15-30 sec or until warm + soft

Finely chop ½ onion + cilantro; add to a small bowl with salt/pep + fresh lime juice

Add meat to tacos with crumbled feta; serve with a side of cilantro onions + hot short rib consume for dipping—wow, that looks great!
