I have this recipe from Gourmet Grains, Beans and Rice for Polenta Crust
I have tried it and it can be a finger food. It is firm. Polenta is
made of cornmeal. Here it is:
nonstick cooking spray
1 1/2 cups yellow cornmeal
1 cup cold water
1 cup boiling water
1/2 teaspoon salt to taste
1/2 cup grated parmesan ( optional for me)
Spray a 9 inch pie pan with nonstick spray. Preheat oven to 375. Place
cornmeal in a small bowl. Add cold water and stir until well mixed.
Stir cornmeal mixture into saucepan of boiling water. Cook, stirring
over low heat until thickened, 3 to 5 minutes. Remove from heat and
stir salt and Parmesan.
Spread cornmeal mixture to form a crust in the greased pan, using wet
hands or a spatula. Spread evenly across bottom and up sides. Bake
uncovered for 30 miutes.
I make this crust on a rather large square pan and do not shape into a
pie, I, then cut into squares.
Toppings can consist of sauteed green and yellow peppers , mushrooms ,
