Heat oil in med. saucepan over med. heat. Add leek and tomatoes (or bell peppers, or any veggies you want really); cover and cook 5 mins or until tender. Stir in quinoa and garlic, and cook, uncovered, 3-4 mins, or until grains start to turn opaque. (They will not fully be cooked yet.) Add 3 cups water and season with salt and the Seasoning Salt (I like Lawry's or Everyday Seasoning). Cover and reduce heat to med-low and simmer 5-10 more, or until most liquid has been absorbed. Remove from heat and let stand 5 mins. Preheat oven to 350 F. Coat 13x9 inch dish with cooking spray. Whisk together eggs and milk in large bowl. Fold in quinoa mixture and cheese. Stir very well and let some of the cheese melt. Transfer to prepared baking dish and if using Panko Crumbs or Bread crumbs add now and bake 30-35 mins, (or until browned around edges.) Now you can toss with many toppings, some ideas: salsa, scallions, sour cream, and hot sauce! I serve with a side of steamed broccoli or a salad and a nice slice of good hearty bread.
