Cook pasta in boiling salted water according to package directions for “al dente.” Reserve 1/4 cup pasta water.
While pasta cooks, heat oil in a large skillet over medium-high. Add shallot and garlic and cook, stirring often, until tender, 3 to 5 minutes. Stir in lamb and cook until browned, about 3 minutes. Stir in paprika, cumin, coriander, cinnamon and cayenne, then tomatoes. Bring sauce to a simmer and cook, stirring occasionally, until liquid reduces, about 8 minutes. Stir in reserved pasta water. 3. Toss pasta with sauce and serve topped with feta and mint.
