Grilled Portabello and Tomato Sandwich Recipe

"One of my favorite summer (because of the fresh tomatoes), but basically any time of the year ... sandwiches. It is a nice alternative to a burger, and just as good. And, this is perfect to entertain with as well. Take advantage of summer tomatoes and baby greens to make this the perfect sandwich. I like to make this on a baguette or focaccia bread, and then cut in individual slices. It is the perfect BBQ, party food. Prep time does NOT include marinating time. You can also use a vegetarian cheese substitute if you want or similar for the mayo if you are concerned. And this can also be made on an outdoor grill as well. "

Step by Step Method

Step 1

Aioli ... Add the mayonnaise, basil, thyme, and garlic to a small bowl and mix. Set to the side and refrigerate until ready to use. Don't worry if it makes a bit more than you need - it is great on any type of sandwich.

Step 2

Marinade ... Add all the ingredients to a ziploc bag or small glass (non-reactive dish) and add the mushrooms. I prefer to remove the stem and clean the gills; that is up to you. Marinate at least 30 minutes but no more than 2 hrs.

Step 3

Mushrooms ... Preheat the broiler and add the mushrooms to a sheet pan lined with foil or parchment paper. Add the mushrooms and cook for 5-7 minutes (second shelf down, so they don't burn) per side until lightly brown - tender - but, still firm. Once they are cooked remove to cool slightly and then thick slice; about 4-6 slices per mushroom.

Step 4

Sandwich ... Cut the baguette in half lengthwise. If using the focaccia that is not necessary. Toast under the broiler as well - just a few minutes until lightly golden brown. Once the bread is toasted, slather the aioli on both sides of the bread (cut side); then top with the mushrooms and peppers on one side; and mushrooms and onions on the other side. Top with cheese slices on both sides, and back under the broiler for just a minute or two to melt. Then add the tomato slices to one side (and season with salt and pepper), the greens to the other side, and put the two halves together. Use toothpicks to hold the sandwich together and slice.

Step 5

Serve ... Even meat lovers will enjoy this sandwich. It makes 4 nice very size sandwiches or approximately 8 snack size sandwiches. As I mentioned, this can be served as a snack, appetizer, party food, lunch, or dinner. Serve with a cup of soup, or even corn on the cob and your favorite summer salads for a nice dinner. ENJOY!
