My favorite hot breakfast grain is quinoa (ok, it's a seed)
I think it was cyclo who described his receipe, and although it's not the same, one can tinker with it to suit ones taste.
You must remember to to put the uncooked quinoa in a bowl of water first, and rub it between your hands, to take off the bitter coating (keeps the birds from eating it), then rinse through a fine sieve.
Then, you just cook it for 20 minutes in milk or soy milk, using the same proportions as you do with rice, 1 cup quinoa to 2 cups liquid. I actually add more liquid, as it soaks up the milk pretty good. While it's cooking I add honey, cinnamon, allspice, raisens, or whatever seems good to you. After it's cooked I like to add peanut butter, banana, berries, etc.
It keeps well. You can make a big batch, and it will last for a few days.
It's the type of thing you can eat anytime day or night. Quinoa is unique in that it's got all the amino acids to make it a complete protein.
I think I'll make up a batch in the morning.
