Indian Chicken and Potatoes

We recorded Baby making this and I haven't written down the recipe yet, but you can watch it here.

I have FINALLY written down this recipe.

1/2 kg chicken breasts-cubed (3-4 depending on how big they are)
3 tomatoes-diced
2 onions-chopped
handful of coriander leaves
3-4 potatoes-cubed
1/2 teaspoon salt
1/2 teaspoon chili powder
2 1/2 teaspoons coriander powder
1/4 teaspoon tumeric
1/2 teaspoon Garam Masala (curry)
1 1/2 teaspoons Garlic/Ginger paste
    (If you can't get the mixed paste, use 1 teaspoon garlic paste and 1/2 teaspoon ginger paste)
1/4 cup vegetable oil
Brown the onion in the vegetable oil in a large pot. Add the Ginger/Garlic Paste. Mix well and add chili powder, coriander powder, tumeric, and garam masala. Add a small amount of water and mix well. Add coriander leaves and stir. Stir in tomatoes and  salt and cover to boil about 4-5 minutes. Once the tomatoes are boiled down add chicken and potatoes. Stir well and add 1 3/4 cup water. Let boil until chicken and potatoes are cooked through.
