*Check for ingredients if needing to be low fodmap, I have seen some with onion and garlic in them. Trader Joes and Simply Organic are two good ones.
*My brother likes a spicy curry powder that I buy in bulk at a health food store. So go for that if you like spice!
*To make a double batch, double the chicken, curry powder, ginger, add 1/2 teaspoon more salt, and more garlic. Use the same amount of tomatoes and coconut milk. The cooking time stays the same!
*For stove-top. Place tomatoes, entire can of coconut milk, garlic oil, salt, curry powder, and ginger in a sauce pan. Put the chicken thighs in making sure they are fully covered. Place over medium heat and bring to a simmer- about 5 minutes. Reduce heat to medium-low, cover and cook 13 minutes stirring regularly. Remove chicken to a cutting board and leave the sauce to keep cooking. Chop chicken and place it back in the pan. Remove from heat and serve.
