Have you tried quinoa? I discovered it earlier on this year and I love it. It's a whole grain (actually a seed), it's a complete protein, which makes it filling and it's free from gluten and cholesterol. Plus, it's pretty delicious!
Here is my recipe for a super easy supper. I cook this for myself with enough next over for a generous lunch the next day. It's great cold as a salad box.
500ml Vegetable Stock
1 x Red Pepper, seeded and sliced
1 x Yellow Pepper, seeded and sliced
A handful of broccoli florets
A handful of green beans
A dash of olive oil
Simply heat the olive oil in a wok, and add the peppers, broccoli and green beans, quickly stir frying until softened. Add the dry quinoa to the mixture. Then add the stock and bring to the boil. Reduce to a simmer until all of the liquid has been absorbed - about 10 minutes.
