Bistek Tagalog (Filipino Beef with Lime Soy Sauce)
Thin beef and thick onion rings are tossed in a salty, tangy sauce of soy sauce and lime juice, a regular weeknight dish with rice in Filipino homes. It is the Philippine version of Spanish bistec, and there calamansi is squeezed in where wine or vinegar would go; lime takes its place in this recipe. The onions cook only until translucent with lightly browned edges and keep some crunch.
