Step 1

Lightly oil an 9 inch pie dish and set aside.

Step 2

Heat the olive oil in a medium skillet over medium heat. Once hot, add onions and cook, stirring frequently until soft and translucent, about 5 minutes.

Step 3

Add the red pepper flakes, garlic, and orange pepper and cook for 2 more minutes. Finally, add the spinach and cook for 5 more minutes, until everything is cooked and heated through.

Step 4

In a medium saucepan, bring the water, salt, tarragon, mustard powder, and black pepper to a boil and slowly whisk in cornmeal. Stir constantly with a wooden spoon until mixture boils and spits cornmeal out all over the place, about 1-2 minutes.

Step 5

Pour the spinach mixture into the cornmeal and quickly mix until well incorporated. Pour everything into the prepared pan and press down evenly to smooth the top. Let cool 10 minutes before slicing into 8 pieces. Serve immediately.
