Healthy ulam | adobong sitaw with tofu

Adobong Sitaw is a delicious Filipino dish. "Sitaw" is indeed the Tagalog word for string beans (also sometimes called yardlong beans because they can grow quite long!). And you've nailed the description - it's cooked "adobo style," which means it's braised in a savory sauce of soy sauce, vinegar, garlic, and peppercorns.
