For our Meatless Monday healthy lunch idea, try some of your favorite pasta with pesto sauce. Try a gluten-free pasta if you can. Trader Joe's makes some of the best GF pastas out of brown rice.
The cool thing with pesto is that it can be made with different herbs or greens. Traditional pesto is made with basil, but I've tried pesto made with cilantro, arugula, spinach, and sage. Yum!
