Quinoa Veggie Burgers with Homemade Tzaziki Sauce

I've been feeling a little guilty about all the creamy pastas and fish and chips I have been eating lately, so I thought I would make some healthier fare this week.  I saw a recipe in Chatelaine Magazine for quinoa burgers and decided to try them out.  The recipe had mushrooms in it, which I just don't like, so I had to change the recipe a bit, but they still turned out amazing.  I served them with yogurt tzaziki sauce and a fresh salad of  lettuce, cucumbers, and tomatoes with some greek-style potatoes on the side.  Everything was so good, and the burgers have a lot of taste to them.  I'm not sure how well they would hold up on a bun, but with a salad they were great.  The tzaziki I made is a sauce I've been making for quite a few years, but I made it healthier by making it with yogurt instead of the sour cream and cream cheese I usually use.  The tzaziki is great as a dip with pita bread and vegetables as well, so it doesn't hurt to double the batch.  If you are not a huge fan of garlic you may want to decrease the amount to one clove as this is a pretty garlicky sauce.
