Break up ½ the pork into bite-size pieces (save remaining for lunch tomorrow); heat a skillet over med-high + sear pieces 3-4 min, turning half way through until meat is crisped and hot; set aside

In batches, heat 4 tortillas in skillet over med-high, 30 sec or until warm

Divide pork to tortillas, add on 1-2 tbsp guacamole to each, thinly slice half an onion + top tacos along with a squeeze of lime
