Detailed Directions and Instructions
Roast the Mushrooms
Preheat the oven to 450°F (232°C). In a large bowl, toss the sliced mushrooms with avocado oil and Cajun seasoning until they are evenly coated. Spread the seasoned mushrooms out in a single layer on a sheet pan. Roast in the preheated oven for 20–25 minutes, or until the mushrooms are golden brown and tender, stirring halfway through for even cooking.
Prepare the Horseradish Aioli
In a medium mixing bowl, combine 1/2 cup mayonnaise, 1 small clove of grated garlic, 1–2 teaspoons of horseradish sauce, and 1–2 teaspoons of lemon juice. Add salt to taste. Mix the ingredients thoroughly until well combined. Taste the aioli and adjust the horseradish and lemon juice according to your preference.
Assemble the Sandwiches
During the final few minutes of roasting the mushrooms, place slices of your chosen bread on the same pan to toast lightly. Once the bread is toasted, remove it from the oven and split each piece in half. If desired, spread pesto rosso on the bottom half of the bread. Layer on the roasted mushrooms, followed by slices of Havarti cheese. If you want the cheese melted, return the sandwiches to the oven for a brief period. Top with a handful of arugula that has been tossed with olive oil and lemon juice, then cap with the top half of the bread that has been spread with horseradish aioli.
