Prep the produce: Rinse and gently pat dry the butter lettuce leaves so they hold their shape as cups (wet leaves will wilt). Halve and pit the avocado and scoop into a small bowl; mash lightly with a fork and stir in the lemon juice and a pinch of salt to prevent browning and brighten flavor. Dice the tomato and cucumber and set aside separately for a fresh garnish that adds crunch and acidity.

Warm the roasted carrots: If your roasted baby carrots are cold, warm them in a skillet for 2–3 minutes with a drizzle (about 1 tsp) of olive oil and a pinch of salt to revive their caramelized edges and release their sweetness. Warming them helps meld textures with the hot turkey and prevents a flavor clash between cold carrots and warm filling.

Heat the pan and bloom the spices: Place a 10-inch skillet over medium-high heat and add 1 tbsp olive oil. When the oil shimmers, add the minced garlic and the ground cumin and cook for 20–30 seconds, stirring constantly; this briefly toasts the cumin and releases its nutty aroma (blooming spices in oil makes them more fragrant and flavorful). Watch carefully so the garlic doesn't brown—browned garlic becomes bitter.

Cook the turkey: Add the 6 oz ground turkey, breaking it into small pieces with a wooden spoon. Spread into an even layer and let it sear undisturbed for 1 minute to develop some caramelization, which adds savory depth. Then continue to cook, stirring occasionally, until no pink remains (about 4–5 minutes total). Season with 1/2 tsp salt and 1/8 tsp black pepper while it finishes cooking so the meat is seasoned through.

Combine turkey with carrots: Add the warmed roasted carrots to the skillet and toss gently to combine. Let them mingle for a minute so the turkey absorbs some of the carrots' roasted sweetness. Taste and adjust seasoning—add the remaining 1/4 tsp salt and remaining pinch of pepper if needed. The goal is a balanced savory-sweet filling with a touch of warmth from cumin.

Assemble the lettuce cups: Spoon a heaping 1/4 to 1/3 cup of the turkey–carrot mixture into each butter lettuce leaf. Dollop 1–2 tablespoons of the mashed avocado onto each portion; the creaminess of avocado cools the warm filling and contributes a rich mouthfeel that makes these wraps feel indulgent.

Top with fresh accents: Scatter diced tomato and cucumber over the avocado (about 1–2 tablespoons each per wrap) to add freshness and a bright, acidic counterpoint to the rich avocado and savory turkey. Finish with a light drizzle (about 1 tsp total per serving) of good olive oil and a final sprinkle of black pepper and red pepper flakes if using.

Serve immediately: Arrange the lettuce cups on a platter and serve right away so the lettuce stays crisp. If you need to hold them a short while, keep components separate and assemble just before serving to avoid soggy leaves.

Cleanup and leftovers: Leftover turkey filling will keep in an airtight container in the fridge for 2–3 days. Store mashed avocado separately (with extra lemon juice) to minimize browning; reheat the filling briefly before assembling to restore warmth.
