I’m not a huge sandwich person, and I rarely seek them out, but I haven’t been able to stop thinking about this flavor bomb of a sandwich I made recently. Garlicy pesto, meaty mushrooms, tangy sourdough, vinegary peppers, creamy mozzarella — this sandwich has it all.
Maybe I’m a sandwich person after all.
- 2 to 3 tablespoons prepared pesto
- 1 pound portobello mushrooms
- 2 tablespoons plus 2 teaspoons avocado oil
- Salt
- 1 12-inch wide sourdough baguette or boule, halved lengthwise, toasted
- 1 garlic clove, halved crosswise
- 4 ounces fresh mozzarella, thinly sliced
- 1/4 cup sliced pickled cherry peppers
- 1/4 cup basil leaves
- Place pesto in a large bowl. Remove stems and gills from portobello mushrooms. Heat 1 tablespoon oil in a medium heavy skillet over medium-high. Arrange half of mushrooms in a single layer in skilled and cook until they start to sizzle, then wrap the bottom of a second heavy skillet that is small enough to nestle into the first with foil and use it to press down on mushrooms evenly. Cook, pressing down, until mushrooms shrink and are deeply browned underneath, about 3 minutes. Remove top skillet; season mushrooms with salt. Turn mushrooms over, add 1 teaspoon oil to pan, and re-cover with foil-lined skillet. Cook, pressing, until second sides of mushrooms are well-browned, about 3 minutes. Transfer mushrooms to bowl with pesto. Repeat process with remaining mushrooms and 1 tablespoon plus 1 teaspoon oil. Toss mushrooms in pesto to coat.
- Rub cut sides of baguette with garlic. Arrange mushrooms on bottom half of bread, then layer mozzarella on top. Top with cherry peppers and basil. Close and cut in quarters to make 4 sandwiches.
