Preheat the oven to 400 degrees F and line a baking sheet with parchment paper.
In a large bowl, combine the ground lamb, harissa paste, cumin, smoked paprika, egg, almond flour, and a pinch of salt and pepper. Mix with your hands until evenly blended.
Divide the mixture into four equal portions and shape each into a small loaf. Place the loaves on one side of the baking sheet.
In the same bowl, toss the cauliflower florets with tahini, olive oil, garlic powder, and additional salt and pepper until well coated. Spread the cauliflower on the other side of the baking sheet.
Bake for 25 to 30 minutes until the meatloaves reach an internal temperature of 160 degrees F and the cauliflower edges turn golden. Remove from the oven and sprinkle with chopped cilantro before serving.
