Grilled Portobello Burgers

What would a chapter on burgers in a vegan cookbook be without a grilled portobello burger recipe? "Grilled Portobello Burgers" (page 118) offers a simple presentation that showcases the wonderful juiciness and chewiness of a grilled portobello served on a bun. Not only are the mushrooms grilled, so too are slices of red onion, and the buns, nice touches that create a total outdoorsy grilling experience. The mushrooms and onions are grilled first, and the marinade is brushed on afterwards. I substituted fresh lime juice for the olive oil in the marinade, but didn't change any of the other ingredients (balsamic vinegar, sugar, salt, and pepper). A nice twist was the use of basil leaves instead of lettuce (or I suppose you could do both). Put everything on a kaiser roll, add a slice of tomato, drizzle on the rest of the marinade, and you've got yourself a perfectly easy and delicious summer meal in the making.
