Final answer:
The Thai Crunch salad can become vegetarian by removing the chicken and fish sauce and possibly adding tofu or tempeh as protein alternatives unless it contains other non-vegetarian elements like shrimp.
Step-by-step explanation:
The Thai Crunch salad can indeed be made vegetarian. The necessary adjustments would be to remove the chicken and fish sauce, which are traditionally non-vegetarian ingredients, from the salad. Substitute animal proteins with plant-based alternatives like tofu or tempeh to maintain the protein content of the dish. As long as the salad does not contain any other non-vegetarian ingredients like shrimp, it can be easily modified to suit a vegetarian diet.
