Wash and dry all produce. Drain and rinse chickpeas. Halve, peel, and very thinly slice shallot. Core, deseed, and finely chop poblano. Dice tomato. Quarter lime.

In a medium bowl, combine vinegar, half the shallot, 1 tsp sugar (2 tsp for 4 servings), a pinch of salt, and 1 TBSP water until sugar and salt are mostly dissolved. Set aside to pickle, stirring occasionally, until ready to serve.

Pat chickpeas dry with paper towels; season with salt, pepper, and half the Southwest Spice (you’ll use the rest later). Heat a large drizzle of olive oil in a large pan over medium-high heat. Add chickpeas and cook, stirring occasionally, until lightly browned and crisped, 4-5 minutes. Transfer to a second medium bowl.

Heat another large drizzle of olive oil in same pan over medium-high heat. Add poblano and remaining shallot; season with salt and pepper. Cook, stirring, until softened, 3-4 minutes. Return chickpeas to pan and stir in tomato paste, stock concentrate, remaining Southwest Spice, and ¼ cup water (½ cup for 4 servings). Cook, stirring, until chickpeas are coated in a thick sauce, 2-3 minutes.

Wrap tortillas in damp paper towels and microwave until warm and pliable, 30 seconds. In a small bowl, combine sour cream and a squeeze of lime juice. Season with salt and pepper. Stir in water 1 tsp at a time until mixture reaches a drizzling consistency.

Divide filling between tortillas. Top with tomato, Monterey Jack, crema, and as much pickled shallot as you like. Serve with remaining lime wedges on the side.
