The 'migas' isn't a side dish here — it's bread torn up and fried in the same fat as the pork ribs, so it soaks up all the meat drippings.
Stale bread is crumbled and pan-fried in pork fat and garlic until it forms a dense, savory cake, served alongside grilled pork ribs (entrecosto). A common sight at Alentejo village fairs and market food stands.
