Portabello mushrooms are a natural for vegetarian sandwiches. They have a great “meaty” flavor but are low in calories and fat.
And they’re easy to cook--just roast them in the oven or on the backyard grill. If you’re grilling them, make sure to cut the mushroom slices large enough that they won’t slip through the grate, and cut the squash on the diagonal. Whether you cook indoors or out, you’ll want to try these quick, easy sandwiches again.
You can find sun-dried tomato paste in tubes at well-stocked supermarkets and specialty stores. Keep it on hand for these sandwiches or use it in dips and spreads.
