In a sauce pan or pan, heat a teaspoon of cooking oil and saute the garlic and onions.
Add ground meat, season with sea salt and pepper and cook until browned.
Discard any excess oil, especially if the ground meat is not lean or drain the meat then put back in the pan.
Add the tomato sauce and 1 and 1/2 to 2 cups of water.
Season with fish sauce (patis) or sea salt, it may seem watery at this stage but don't worry, most of it will evaporate and get absorbed by the veggies.
Cover the pan and cook ground meat for about 15 minutes.
Add in the diced potatoes and carrots.
Cook covered until almost tender for about 10 minutes.
Add the corn and frozen peas.
Cook for 5 minutes.
Taste it and adjust to your preference. That't it!
Serve this delicious dish with rice.
