I make this stuff on a weekly basis. I make it using chicken, and chicken broth instead of water. Included veggies are carrots, onions, potatoes, and green bell pepper (capsicum).
I cook chicken (1lb, cubed) with onion (1, large dice), salt, and pepper (to taste, aprx 1 tsp each). Then I add all the veggies (1 carrot, 1 pepper, equal amount of potatoes as chicken) and chicken broth (1 can), then add water until the potatoes are covered nicely and boil for 10 minutes. Meanwhile, I put the rice on (2cups w/ 3cups water or equivalent) (sticky rice is the only way to go on this, IMO). After potatoes are boiled, I put chunks of the bullion curry cubes until it reaches the desired consistency and serve with rice. Sometimes I add a splash of milk to add some richness, and I almost always put a splash of soy sauce to add color and saltiness. I like to compact as much rice as I can into half of a bowl and fill the other half of the bowl with curry. Obviously during the chicken cooking process, you can add whatever spices you choose to flavor the chicken pieces.
