Prep Work: Chop onion, mushrooms and greens; store separately. Cook quinoa.
Heat dry quinoa in a little (1 Tbsp.) oil in a skillet. Stir frequently for a few minutes while quinoa "roasts" to enhance flavor.
Add water and broth to skillet and bring to a boil. Reduce heat to simmer and cover quinoa for 15 min., or until liquid absorbed. Season with salt and pepper and a little butter or olive oil if desired.
While quinoa cooks, heat 2 Tbsp. of oil in another skillet. Saute onion 2 min., then add mushrooms and garlic for another 3 min.
Add greens with crushed red pepper and another 1/4 c. broth or water (for yield of 6). Cover pan and simmer for 10 min. or until greens are tender.
Add a shaved carrot. Serve vegetables over 1 c. of quinoa and top with leftover sirloin if desired.
