In a medium bowl, combine the lemon juice, olive oil, Dijon, honey, salt, crushed red pepper, and pepper. Add the mushrooms and toss to coat.
Allow to marinate for 4 to 8 hours, stirring occasionally. When ready to serve, add the tomatoes, carrots, and fresh chopped chives to the mushrooms. Adjust the seasonings with salt and pepper and place in a serving dish.
