Here's how I make it for 1:
1/2 C. Brown or White Rice
1 1/2 C. Water
Microwave on high for 20 minutes. (I found brown rice takes a bit longer, with a bit more water, so you may have to experiment with the amount of water.)
When the rice is cooked, add 1 Tbsp. of butter and stir to incorporate. Then, break 1 raw egg into the hot rice and stir vigorously.
The egg gently cooks, and blends with the melted butter. Pinch of rice, pinch of pepper, dash of cayenne, dash of onion powder.
Garnish with chopped mushrooms, chives and/or green onions. Voila! Breakfast in a bowl!
