In another pot over medium heat, heat oil. Add onions and garlic and cook until tender and aromatic.

Step 5

Add tomatoes and cook, mashing with the back of the spoon, until softened.

Step 6

Add fish sauce and continue to cook for about 1 to 2 minutes.

Add cooked mung beans including liquid. Bring to a boil.

Step 8

Add pork cracklings and continue to cook until softened. Season with salt and pepper to taste.
