"We're having sidewalk weed again." "Oh joy," said the husband. Not really. He didn't say that. He just ate it. Until a few years ago, he didn't know that the weed he saw growing wildly along the sidewalk and on vacant lots was edible. Ha! Then he met me. Specifically, I'm talking about purslane, also known as pigsweed. Portulaca oleracea is its scientific name. The Mexicans call it verdolaga. The Mama calls it kakalangay (an approximate Ilocano spelling to what I hear). Not ngalog, she says. That's something else. Have I lost you? I'm talking about the fleshy, pinkish looking weed that spreads out on the ground. It look anemic and very unappetizing. Water it, and voila, you have what you see in that photo above. It is good to eat. Very good to eat, in fact. Tasty, too. The weed, okay the herb, is high in vitamin C, vitamin A, calcium, potassium, and a whole bunch of the B-vitamin complex. It's also rich in omega-3 fatty acid goodness. Be
