First chop up the onions. Put a frying pan big enough to handle the whole shebang on at medium and add 3 Tbsp. extra virgin olive oil. add 1/2 tsp. salt and 1/4 Tsp. black pepper.
When the onions get translucent add the frozen peas and the leftover rice from the freezer. Push the peas and the onions aside and let the rice thaw in the middle. If you are using rice that is not frozen just go with it.
Toss it all together and when the peas and rice are as warm to the touch as you want them,,,serve it up! There are your carbs and veggies all in one shot and it's gluten free.
