Method:

1. Combine the flour, 1/2 teaspoon of salt, and a bit of water in a bowl, adding just enough water to make a pancake-like batter. Whisk together until smooth. 

2. Coat each potato piece with the batter.

3. Deep-fry in oil until golden brown on all sides.

4. In a separate skillet, heat the minced green chilies, minced garlic, soy sauce, chili sauce or hot sauce, and tomato paste in a bit of oil, stirring well. 

5. Add the sugar, salt, pepper, and the potatoes, and stir well to coat the potatoes with spices. 

6. Remove from heat and garnish with fresh chopped cilantro and chopped green onions.
