Heat oil in a large nonstick skillet over medium-high heat. Sprinkle mushrooms with salt and pepper. Add mushrooms to pan; sauté 4 minutes or until tender, turning once. Add garlic to pan; sauté 30 seconds. Remove from heat.
Combine cheese and Just Mayo, stirring well. Spread about 2 tablespoons cheese/mayo mixture over bottom half of each roll; top each serving with 1/2 cup arugula and a few slices of peppers. Place 1 mushroom on each serving, and top with top halves of rolls. Enjoy!
