Instructions

1. Preheat oven to 400.
2. Heat the oil in a large skillet or dutch oven over medium-hight heat. Add the onions, salt, and pepper. Saute until the onion softens and starts to become translucent, about 5 minutes.
3. Add the ground turkey and cumin and continue cooking until turkey is cooked through, about 5 minutes. Drain about half the fat from the ground turkey mixture and discard.
4. Add the spinach and cook until spinach is just wilted, about 2-3 minutes. Turn off the heat and add the black beans. Use a pastry cutter to mash some of the beans and then add the mascarpone and mix thoroughly.
5. Spoon about 1/4-1/3 cup of filling onto the middle of a tortilla. Roll up taquito and place seam side down on a lightly oiled baking dish. Repeat with the remaining tortillas.
6. Use a pastry brush to brush a light coating of olive oil onto each taquito. Sprinkle with some fleur de sel to finish.
7. Bake at 400 for about 25 minutes, until taquitos are lightly golden brown.
