Brown or white rice, cooked
Oil -- I use canola. Olive would be fine.
Sea salt.
Black pepper
Or any other favorite spice -- paprika, chili powder, cumin, ground red pepper, oregano, etc.
Recipe
In a stove top pan, heat oil for a minute, about 1 tbsp. Scoop out 2-3 cups of the pre-cooked rice and place in the pan. Use a utensil to separate the rice and mix it well with the oil. Add 1 tsp sea salt and a few dashes of the pepper or any other spice you think might work. My kids like all of them, so I'll mix it up day to day on their foods. Just heat this up, tossing it around a few times to make sure it's coated and the spice is mixed well.
You only have to heat this a few minutes. Then serve.
