2Heat 1 tablespoon of the oil in a large frying pan over medium heat until shimmering. Add pecans, stir to coat in oil, and cook, stirring occasionally, until nuts are fragrant and golden brown, about 8 minutes. Remove from heat, add 1/2 teaspoon of the salt and 1/2 teaspoon of the smoked paprika, and stir to evenly coat the nuts. Add to the bowl with the reserved spinach.
3Return the pan to medium heat, add 1 tablespoon of the oil, and heat until shimmering. Add sweet potato, remaining 1 teaspoon salt, and remaining 1/2 teaspoon paprika and stir to coat the sweet potato. Cook, stirring occasionally, until sweet potato just gives way when pierced with a knife and is starting to brown at the edges, about 10 minutes. Add to the bowl with the nuts and spinach.
4Return the pan to medium heat, add remaining 2 tablespoons oil, and heat until shimmering. Add shallot and cook until just golden brown, about 1 minute. Remove from heat, add vinegar, brown sugar, and mustard and whisk to combine. Pour vinaigrette over spinach, nuts, and sweet potato and toss to coat. Serve immediately.
Sweet potatoes are absolutely marvelous—they’re incredibly versatile, naturally sweet, loaded with nutrients and fiber, and low in calories. Really, what’s not to love? Here, they're simply sliced and cooked to make the perfect crust for a quiche.
Sweet Potato Casserole
This is not your mother's sweet potato casserole (and that's a good thing). This version is only lightly sweetened, tender rather than gloppy or mushy, and accented with a hint of ginger. It's still topped with browned, gooey marshmallows, though, because some traditions are worth sticking to.
