• Wash and dry produce. • Halve, peel, and finely dice onion. Core, deseed, and finely dice green pepper. Zest and quarter lime. Trim and discard root end from lettuce; separate leaves. Gently crush tortilla chips in their bag into small pieces.

• Heat a drizzle of oil in a large pan over medium-high heat. Add onion, green pepper, and pork*. Season generously with salt (we used 1⁄4 tsp; 1⁄2 tsp for 4 servings) and pepper. Cook, breaking up meat into pieces, until pork is lightly browned and onion is slightly softened, 4-5 minutes. • Add Fajita Spice Blend; cook, stirring, 30 seconds. Stir in stock concentrate, 1⁄2 tsp sugar, and 1 TBSP water (use 1 tsp sugar and 2 TBSP water for 4). Cook, stirring occasionally, until pork is cooked through, 2-3 minutes more. Simply cook through this step as instructed, swapping in turkey or beef for pork.

• Meanwhile, in a small bowl, combine sour cream, lime zest, and juice from one lime wedge. Add water 1 tsp at a time until mixture reaches a drizzling consistency. Season with salt and pepper.

• Remove pan with pork filling from heat; sprinkle with Mexican cheese blend. Cover pan until cheese melts, 1-2 minutes. • Divide lettuce leaves between plates; fill with pork filling. Drizzle with lime crema and sprinkle with crushed tortilla chips. Serve with any remaining lime wedges on the side.
