Sandwiches and Wraps: Grilled Veggie-Portobello Mushroom Burgers

Dec 23, 2010 This was delicious, even though I forgot the blue cheese. Great combo of veggies! I used homemade balsamic vinaigrette, and I didn't have time to marinate, but they still had plenty of flavor. Also, since it's too cold to grill, I roasted the veggies in the oven at 425. Because my buns were way too small for the huge portobellos I had, I used sprouted-grain bagels, which aren't as dense as regular bagels but are thicker than buns and held up well to the juicy veggies. I'm making again this week--and this time I'll remember the blue cheese!
