Instructions: Puree basil, 1/4 cup mayonnaise, lemon juice, and mustard in processor until smooth. Transfer to small bowl; mix in remaining 1 cup mayonnaise and season to taste with salt and pepper. (Can be made 1 day ahead. Cover and refrigerate.)

Preheat oven to 350 degrees. Arrange pancetta in single layer on rimmed baking sheet. Cook until pancetta is just crisp, about 15 minutes. Transfer to paper towels to drain. Reduce oven temperature to 200 degrees.

Sprinkle all green tomato slices with salt and pepper. Place 1/2 cup flour in shallow bowl. Mix remaining 1/2 cup flour with cornmeal in another shallow bowl to blend. Working with 1 green tomato slice at a time, coat with flour, then egg, then flour-cornmeal mixture. Transfer to baking sheet. Line second baking sheet with paper towels.

Heat oil in heavy large skillet over medium-high heat. Working in batches, fry green tomatoes until golden brown, about 2 minutes per side. Using slotted spoon, transfer to prepared baking sheet; sprinkle with salt and pepper. Keep warm in oven.

Sprinkle red and yellow tomatoes with salt and pepper. Place 1 fried green tomato slice on each of 6 plates. Spread each with 1 teaspoon basil mayonnaise, then top with 2 tablespoons arugula, 1 slice pancetta, 1 slice red tomato, another fried green tomato, 1 slice yellow tomato, pancetta, and another 2 tablespoons arugula. Spoon 1 teaspoon mayonnaise over arugula, then top with remaining fried green tomatoes. Spoon 1 teaspoon mayonnaise atop green tomato. Finish with remaining pancetta and serve.

This recipe yields 6 servings.

Comments: Margaret DeMatteo of Stirling, New Jersey, writes: "My husband recently took me to the nearby Perryville Inn to celebrate my birthday. We had a fabulous BLT appetizer made with layers of fried green tomatoes, pancetta, and basil mayonnaise. I would greatly appreciate it if you could get the recipe."
