Here is what I have made:
1. Roasted Potato and Tomato Salad (from Moosewood Daily Special)
2. Southwestern Corn Slaw
3. Black Bean and Corn Salad
4. Quinoa and Black Bean Salad (Not pictured)
Salad seems like a great item to investigate if you are gluten-free - there are lots of salads out there that don't even need to be adjusted, you just need to double-check all your ingredients.
