Back when I still ate grains (recently went Keto for weight loss and see if such helps my accursed eczema, which it seems to be doing), my favorite steamer recipe was:
Enough chicken stock to replace the water needed for:
.5 cup of dry brown rice
1 cup of stir fry frozen veggies
.5 cup of frozen mixed veggies (peas/carrots/corn)
2 small chicken breasts
NaCl/Black Pepper/Curry Powder/Cayenne pepper to taste
Steam for 50-55 minutes to ensure chicken is fully cooked.
