Preheat oven to 325°F. Spread pecans, sesame seeds, coriander seeds, and cumin seeds on a rimmed baking sheet and bake for 9 to 10 minutes until lightly toasted. Cool and pulse in a food processor with salt and Aleppo pepper. Store in an airtight container.
Grind chiles and cumin seeds in a spice grinder. Mix with softened butter, lime zest, lime juice, salt, garlic, smoked paprika, and black pepper in a mixer until creamy. Store in fridge.
Combine Chile-Lime Butter and lime juice in a bowl. Preheat grill to high. Toss cabbage leaves with olive oil, salt, and pepper. Grill leaves for 2 to 5 minutes until charred, flipping often.
Toss charred leaves in the butter mixture, season to taste, and serve topped with Pecan Dukkah and fresh herbs.
