Step 1: The cooking process is straightforward sautéing. In a large casserole or pan, heat the oil in medium flame.
Step 2: Fry the garlic, followed by ginger. Add in the chopped tomatoes and continue frying until soft and mushy.
Step 3: Add in mussels and continue sautéing until it renders out its own liquid and shells starts to open.
Step 4: Continue simmering with liquid that comes out. Add some more hot water or better yet, rice washing (second wash) if you want it soupier.
Step 5: Add ground pepper and season it with salt to taste. Mussels usually packed some salty liquid inside the shell so taste and watch out adding salt.
Step 6: Add the petchay or any veggies of your choice and continue simmering until the vegetable is cooked through.
Step 7: Transfer in a shallow bowl and serve hot along side with some fried fish and steamed rice.
