Preheat oven to 375 degrees, and line a baking sheet with foil.
Cover the frozen pie crust with foil, fill it with pie weights, place on the prepared baking sheet and pre-bake for about 25 minutes; remove from oven and allow to cool.
Place the chopped rhubarb in a large bowl and toss with 1/4 cup of sugar and set aside.
Whisk together the remaining 1-1/4 cup sugar, flour, eggs, butter and cream until combined.
Pour the filling into the pre-baked crust.
Scatter the rhubarb evenly on top, discarding any liquid at the bottom of the bowl.
Bake the pie for 60 to 65 minutes, or until the edges of the filling are set but the center still wobbles slightly. Cover the edges with foil about 45 minutes through baking to make sure it doesn’t burn.
Cool the pie on a wire rack.
Once the pie has cooled completely, cut and serve. Store leftovers in the refrigerator.

Prepare the pie crust by pricking the bottom and sides with a fork, then sprinkling about 1/4 cup of shredded cheese evenly in the bottom.
Bake the crust for about 10 minutes, then remove from oven and allow to cool slightly.
Meanwhile, in a large skillet melt the butter over medium heat.
Add the onion and sauté for 2-3 minutes.
Stir in the spinach and cook until bright green and wilted.
In the bowl of a food processor (or blender), combine the eggs, ricotta, heavy cream, seasonings and remainder of Italian cheese.
Blend until smooth.
Spread the spinach and onion mixture evenly over the pre-baked crust.
Pour egg mixture on top until filled to the top (pour any excess in silicone baking cups and bake alongside quiche).
Bake the quiche in the preheated oven until the center is set and the top is lightly browned, about 45 minutes (cover the crust with foil for the last 5 minutes or so if getting too done).
Allow to stand for 10-15 minutes before slicing and serving.
