1 small head orange cauliflower, stems removed and florets cut into bite-size pieces
2 large Yukon Gold potatoes, peeled and cut into 1" cubes
½ cup reduced-fat sour cream
8 ounces frozen chopped spinach, thawed and squeezed to remove excess moisture
sea salt and freshly ground black pepper, to taste
Filling:
2 tablespoons olive oil
1¼ pounds ground turkey
1 large onion, diced
3 carrots, peeled and diced
4 garlic cloves, minced
4 teaspoons tomato paste
2½ tablespoons brown rice flour (see notes)
1¼ cups chicken broth
2½ teaspoons Worcestershire sauce
2 teaspoons chopped fresh parsley
2 teaspoons fresh thyme leaves
1 teaspoon chopped fresh rosemary
1¼ cups frozen peas
8 ounces frozen chopped spinach, thawed and squeezed to remove excess moisture
sea salt and freshly ground black pepper, to taste
Instructions
Make the cauliflower and potato purée topping:
Preheat oven to 400 degrees.
Cut about ¼ inch off the top of the head of garlic. Place garlic on a piece of foil, drizzle with 1 tablespoon olive oil and fold to enclose. Bake for 1 hour and then remove from the oven. When cool enough to handle, squeeze out roasted garlic and transfer to a small bowl.
Bring a large pot of salted water to a boil. Add cauliflower and potatoes and cook, uncovered, until tender, 12-15 minutes. Drain, reserving 1 cup cooking liquid.
Transfer cooked cauliflower and potatoes to a large bowl. Add ¼ cup reserved cooking liquid and purée until smooth. If necessary, add more reserved cooking liquid to loosen the purée.
Add sour cream, spinach, roasted garlic and remaining 2 tablespoons olive oil and stir to combine. Season with salt and pepper to taste.
Make the filling and assemble the pie:
In a large pot, heat olive oil over medium-high heat. Add ground turkey, breaking it into bite-size pieces with a wooden spoon, and cook until browned.
Add onion and carrots and cook, stirring occasionally, until tender, about 5 minutes. Add garlic and cook until fragrant, about 1 minute.
Add tomato paste and cook, stirring constantly, until tomato paste begins to darken, about 3 minutes. Add flour and cook, stirring constantly, for 2 minutes.
Add chicken broth, Worcestershire sauce, parsley, thyme and rosemary and bring to a boil. Reduce heat to medium-low and simmer, stirring occasionally, until slightly thickened, about 10 minutes.
Add peas and spinach and cook until heated through, about 2 minutes. Season with salt and pepper to taste.
Transfer mixture to a 12" pie plate. Spread the cauliflower and potato purée topping over the mixture.
Broil for 5-7 minutes to brown top.
Notes
You can substitute all-purpose flour if it's more convenient.
