In a microwave bowl, add oil and onion. Microwave for 3 minutes.
Add in the tomatoes and spice powders except the garam masala powder and microwave for 5 minutes. Mix well.
Now add the chicken along with salt and 1/2 cup water.
Microwave on closed lid for 15 minutes. You will find the curry to be dry.
Take out the bowl, sprinkle the garam masala, add another 1/2 cup of water.
Microwave for another 3 minutes without lid. Rest for 5 minutes.
Serve warm with plain rice!
For Plain Rice:
Wash the measured basmati rice well. I used one cup. Soak rice for 30 minutes.
Put the rice and double the water - 2 cups (normal temperature) in a large microwave bowl and microwave for 12 minutes.
Leave untouched for 5 minutes.
Fluff up with fork and serve!!!
