Laing is a lesson in what 'vegetable' means at a carinderia. Dried gabi leaves are light and absorb liquid, so 10g of dried leaves swells to a big serving in the pot. Those leaves are about 30 calories. The coconut milk they soak up is the problem: about 100ml per serving at 200 calories, and some cooks finish with coconut cream on top. Kawaling Pinoy's home recipe card comes to 927 per serving, but that uses a full pound of belly and 5 cups of coconut for 6 people.
The pork is the second lever. Carinderia laing usually has small belly pieces or a few flakes of tinapa or dried dilis for flavour. About 30g of belly is 110 calories. The dried fish version is about 40 calories for the same weight, so laing na may daing is closer to 280 per serving. Ask which one it is, because they look the same under the coconut.
The saving grace is that laing is eaten in small amounts. A 40 to 60 peso scoop with 1 cup of rice is about 610 calories, which is a normal lunch. The trouble is when laing is the side to another coconut dish like Bicol Express, and you end up with 870 calories of ulam before the rice. One gata dish per plate is the rule.
