When I first started gardening, I learned an important lesson about squash. Squash will continue to grow and grow until it is picked. You can leave your house in the morning with a 4-inch zucchini on the vine and come home to an 8-incher. For this reason, the first time I grew zucchini and yellow squash, I couldn’t make food fast enough to keep up with my squash yield and ended up sending guests home with a bounty of veggies.

In spite of all of the zucchini I was consuming, I never grew tired of it because of its versatility. This roasted summer vegetable quinoa salad is the perfect place to put your zucchini and yellow squash, whether or not it is straight from the garden.

To prepare the dressing for this salad, I used my Vitamix Blender and my dressing was ready in 2 seconds flat. This high-powered machine makes preparing homemade dressings (and soups, smoothies, and more!) so easy to the extent that I never buy store-bought dressings any more. This is a healthier and tastier way to give your summer salads flavor!

This quinoa salad is full of roasted summer vegetables with and zesty lemon flavor. It works as a great alternative to pasta salads, which can be full of fat from mayonnaise and oils. This healthy salad is very easy to make and only requires roasting some vegetables (you can also grill the veggies) and steaming up some quinoa.
