This sophisticated vegetarian dish offers a delightful contrast between a warm, toasted sandwich and a chilled, vibrant soup. This recipe for grilled heirloom tomato and mozzarella sandwiches with green heirloom tomato gazpacho uses seasonal heritage varieties to create a lunch that is as beautiful as it is flavourful. The green tomato gazpacho is enriched with buttery Marcona almonds, providing a nutty depth that balances the sharp acidity of the vinegar and the fresh crunch of cucumber.

How to make Grilled Heirloom Tomato and Mozzarella Sandwiches with Green Heirloom Tomato Gazpacho
Combine first 8 ingredients and 1 teaspoon coarse salt in processor. Blend to almost smooth puree (some texture should remain). Season with pepper and more salt, if desired. Transfer to medium bowl. Cover; chill at least 3 hours and up to 1 day.
Cut each bread slice into rectangle (about 4 1/2 x 2 1/2 inches). Arrange 4 bread rectangles on work surface. Top bread with half of cheese slices (trimming to fit) and 2 tomato slices. Sprinkle tomatoes with salt and pepper. Top with remaining cheese, then remaining bread; press to compact.
Melt butter in large skillet over medium heat. Add sandwiches. Cover and cook until bread is golden, turning once, about 3 minutes per side. Transfer sandwiches to paper towels. Cut each sandwich in half.
Divide gazpacho among 4 bowls; place on plates. Arrange sandwiches alongside.
