Vegetarian Stuffed Portobellos with Tomato-Shallot Vinaigrette
Summer 2009
Use the grill to celebrate the season’s bounty. Summer in Ontario is all about soaking up every last second of sunshine and warmth. It’s also about making the most of the freshest produce we’ll get to see all year. The velvety “meaty” texture of grilled mushrooms is richly satisfying and full of umami—that savoury je ne sais quoi most often found in proteins. A little kitchen prep ahead of time lets you wow ‘em with minimal effort over the grill. Served with grilled flatbread, this casually elegant dish—with a bright, herby cherry tomato vinaigrette—is an ode to the season of plenty. The inclusion of protein-rich quinoa to classic stuffed portobellos makes these not only delicious, but a nutritious vegetarian meal, too. The tomato-shallot vinaigrette adds the perfect zest to this earthy dish.
