This one if from the Moosewood Cookbook. I have made this several times and it is yummy.
Cauliflower-Cheese Pie (with Grated Potato Crust)
Crust: 2 c. packed, grated, raw potato
1/2 tsp. salt
1 egg, beaten
1/4 c. grated onion
Heat oven to 400.
Set the freshly-grated potato in a colander. Salt it and leave it for 10 min. Then squeeze out the excess water and add it to the remaning ingredients. Pat it into a well-oiled 9-inch pie pan, building up the sides of the crust with lightly floured fingers. Back for 40 to 45 min until brown. After the first 30 min., brush the crust with a little oil to crispen it.
Turn oven down to 375.
Filling: 1 heaping, packed cup grated cheddar cheese
1 med. cauliflower, broken into small flowerets
1 med. clove crushed garlic
1 c. chopped onion
3 tbsp. butter
dash of thyme
1/2 tsp. basil
1/2 tsp. salt
2 eggs and 1/4 c. of milk beaten together
black pepper
paprika
Saute onions and garlic, lightly salted, in butter for 5 minutes. Add herbs and califlower and cook, covered, 10 minutes, stirring occassionally. Spread half the cheese into the baked crust, then the saute, then the rest of the cheese. Pour the egg-milk mixture over and dust with paprika. Bake 35 to 40 min - until set.
