Season chicken generously with 2 tsp salt, the chipotle chili powder, 1 tsp onion powder, 1 tsp garlic powder, and the chili powder of your choice.
Wash the rice until the water runs clear. Drain.
In a large liquid measuring cup, melt the butter and add the chicken stock, tomato passata, 1 tsp salt, 1 tsp garlic powder, and 1 tsp onion powder.
Fill the liquid measuring cup with water until there is a total of 4 1/2 cups of liquid. Mix thoroughly.
Mix the liquid with the rice and put it in the rice maker or pressure cooker.
Place seasoned uncooked chicken on top of the rice, but mostly submerged in the water.
Set the rice maker or pressure cooker to the 'white rice' setting.
The rice and chicken should be finished cooking at the same time. Remove chicken and cut or shred. Serve in large burrito sized tortillas with beans, cheese, and a salsa of your choice.
