Instead of the traditional gefilte fish first course, try this creamy (but dairy-free) dish for Passover.
Heat oven to 350°. In a medium saucepan over low heat, combine 3 tablespoons olive oil and cake meal, stirring until a smooth paste forms. Cook 3 minutes. Whisk in nondairy milk and vegetable stock, and raise heat to bring to a boil. The sauce will thicken considerably. Remove from heat; add spinach and blend well. Season with salt, white pepper, and nutmeg. Cover the pan with plastic wrap and set aside.
In a bowl, combine crumbled matzo and 2 tablespoons olive oil. Work the mixture with your fingers to form a semi-wet consistency.
Grease a casserole dish with oil. Cover the bottom of the dish with ½ cup of sauce. Place fish over the sauce and spoon remaining sauce over the fish. Top with crumbled matzo.
Bake 20 minutes, until the fish breaks when a fork is inserted on the bottom and lifted. Serve at once.
