Meagan, host of Rhymes with Vegan, features a perfect meal for a BBQ in this video. Watch as she makes Tofu/Seitan/Vegetable Kabobs in Chipotle BBQ Sauce, plus Edamame with Toasted Sesame Oil, and Mashed Potatoes with Chives- and everything can be cooked on the grill!
Since Meagan doesn't make a homemade BBQ sauce in the video, I am betting she is using Annie's Naturals Organic Hot Chipotle BBQ Sauce. Annie's has several other flavors in case you cannot handle the heat; Smokey Maple BBQ Sauce, Sweet & Spicy BBQ Sauce, and Original BBQ Sauce. I've had both the Smokey Maple, and the Original and really liked them both.
Annie's Naturals can be found at Whole Foods, Sprouts, and Fry's Marketplace, as well as several mainstream grocery stores.
