What type of sauce might be omitted from the Szechuan tofu lettuce wraps to make them suitable for certain diets?

In the context of accommodating various dietary preferences, spicy yogurt may be the sauce that is omitted from the Szechuan tofu lettuce wraps. Many dietary restrictions, such as those concerning lactose intolerance, vegetarianism, or veganism, make spicy yogurt less suitable for individuals following these diets. By omitting spicy yogurt, the dish can be more inclusive, allowing those who avoid dairy or animal products to enjoy the wraps without compromising their dietary choices.

Regarding the other sauces, soy sauce, teriyaki sauce, and barbecue sauce can often be made with vegan ingredients and may be acceptable for many common diets, including vegetarian and vegan diets, although it's always prudent to check specific ingredient lists to ensure compatibility. However, spicy yogurt is more likely to be incompatible for those with lactose sensitivities or those who do not consume dairy, thereby making it the most likely candidate for omission to accommodate those dietary needs.
