• 2 c. part-skim ricotta cheese
• 1 (9-in.) unbaked pie shell
Preheat oven to 350 degrees. In a 10-inch nonstick skillet over medium-high heat, heat stock or wine and oil. Add mushrooms. Cook, stirring frequently, until browned. Stir in spinach, oregano and thyme. Cover and cook 1 minute, or until spinach wilts. Remove from heat; transfer to colander and drain well.
In medium bowl, combine ricotta and eggs; with wooden spoon, beat until smooth. Add mushroom mixture; pour into pie shell. Bake for 45 minutes, or until firm and lightly browned. Let stand 10 minutes before slicing.
