For a leaner option, substitute ground turkey or chicken, adjusting cooking time slightly if needed. Use fresh lime juice for a brighter flavor. Toast buns lightly before serving for extra texture. For thicker sauce, mix 1 teaspoon cornstarch with 1 tablespoon water and stir in after pressure cooking, then sauté until thickened. Store leftovers refrigerated up to 3-4 days or freeze up to 3 months. Reheat gently and add water or broth if sauce thickens too much.
