I don't really like the texture of quinoa, but it's OK if I mix it 50/50 with short-grain brown rice. So I do that and then make grain bowls. You could do the same with pure quinoa if you like it that way.

Brown rice & quinoa mix
Lentils cooked with ginger, garlic, garam masala
Roasted brussel sprouts, cauliflower, sweet potatoes
Dressing of red wine vinegar, olive oil, and lemon juice
Top with hummus and/or tzaziki

Brown rice & quinoa mix
Red or black beans cooked with garlic, red onion, cumin, chili pepper
Sautéed bell peppers, corn, diced zucchini
Cheese, avocado, cilantro & sour cream (or a cilantro crema dressing) on top

Brown rice & quinoa mix
White beans sautéed with onion, oregano, thyme, basil, garlic, zucchini
Arugula, chopped tomatoes, parmesan
Olive oil, red wine vinegar and lemon juice

I make the various fixings in big batches, and freeze in 1/2 cup containers. Pull out a few containers to thaw, microwave them together at work, and add the fresh/cold stuff and dressing on top.

I didn't like quinoa until I started cooking it in broth instead of water.

101 cookbooks has a good quinoa patties recipe. There’s also a great Deborah Madison recipe with quinoa, corn, black beans and feta stuffed in bell peppers.
Most of the time we just eat it as a rice sub. So any stew or curry you eat over rice, use quinoa instead.

Ditto the "quinoa fried rice" idea. I cook quinoa in chicken broth and while that is cooking I scramble a few eggs in a wok, remove, then cook peppers, onions, mushrooms and anything else I have handy, and then I put the quinoa and eggs back in, and mix in 3-4 tablespoons of soy sauce and a teaspoon of siracha.
