Polenta Stacks with Eggplant, Tomato and Mozzarella

Preparation

1. For polenta:

   Step 1

   Bring 2 cups water and salt to boil in heavy small saucepan. Gradually whisk in cornmeal. Reduce heat to medium-low; simmer until polenta is very thick, whisking constantly, about 6 minutes. Remove from heat. Add cheese and butter; whisk until melted. Mix in basil. Season generously with pepper. Spread in 9x9x2-inch metal baking pan. Chill until cold, about 1 hour.(Can be made 1 day ahead. Cover, keep chilled.)

2. For stacks:

   Step 2

   Preheat broiler. Place eggplant on baking sheet. Brush with oil on both sides; sprinkle with salt and pepper. Broil until brown, about 4 minutes per side. Arrange 12 tomato slices on large plate (discard end slices). Drizzle each slice with a few drops of vinegar. Sprinkle eggplant and tomatoes with oregano.

   Step 3

   Preheat oven to 375°F. Oil baking sheet. Cut polenta into 25 squares. Place 12 squares on sheet. Top each with eggplant round. Cut cheese into 1/3-inch thick slices; place atop squares. Top each with tomato slice (save remaining polenta and cheese for another use).

   Step 4

   Bake polenta stacks until heated through and cheese melts, about 15 minutes. Top each stack with 1 basil leaf.
