Preheat the oven to 425F convection. Line a baking sheet with parchment paper.
Add cauliflower, carrots, olive oil, and ½ teaspoon salt to the baking sheet and toss to coat thoroughly. Spread into an even layer and bake for 20 minutes.
In a medium bowl, add the lamb, nuts, herbs, spices, garlic, and remaining 1 teaspoon salt. Use your hands to thoroughly mix everything together, making sure all ingredients are evenly distributed and mixed in. Form into about 16 balls.
Scatter the apricots or dates all over the sheet pan and nestle the meatballs into the veggies. Bake for 10-15 more minutes or until meatballs are cooked through and browned on top.
Meanwhile, in a medium bowl, whisk together the yogurt, tahini, lemon, cumin, salt, turmeric, and cinnamon until smooth. Whisk in the water, starting with 3 tablespoons. If it’s too thick, add a bit more water and mix again (you want it drizzle-able!). Be sure to taste and add more lemon if needed.
Serve the lamb/veg topped with plenty of sauce, lots of herbs, nuts, and a generous squeeze of lemon.
