I made a fall assortment of grilled recipes from The Vegetarian Grill: 200 Recipes for Inspired Flame-Kissed Meals and was quite pleased with the results.

Sweet potatoes in lime-maple marinade consisted of 1/4 inch slices of sweet potatoes marinated in maple syrup, lime juice, minced garlic, a little soy sauce, and a little bit of mustard.  Extremely flavorful! (I tossed the finished sweet potatoes in the leftover marinade for added potency.)

Grilled Roma tomatoes with pesto and parmesan were good and extremely easy to fix, as was the grilled leek drizzled with a little bit of balsamic vinegar. 

I never would have thought to grill cauliflower (marinated in a little italian dressing), but this too was delicious. 

I definitely recommend the book and look forward to future experiments.
