Pick over and rinse the mung beans, then bring to the boil with the water. Simmer covered over low heat for 35-40 minutes until the beans burst and are tender.
In another pot, render the pork belly in the oil until golden brown.
Add the garlic and onion and cook for 2-3 minutes, then add the tomatoes and cook until they break down.
Add the shrimp and fry for 1-2 minutes.
Pour in the cooked beans with their cooking water, season with fish sauce and pepper, and cook for a further 10 minutes until creamy and stew-like. You can mash some of the beans with a wooden spoon.
Finally stir in the spinach and cook just until wilted. Serve with rice.

Tips
Meat- and shrimp-free, with fried tofu, it's vegetarian.
The mung beans don't need pre-soaking, but soaking does speed up cooking.
