Vegetarian Smash Burger Taco

Why this version is better

Removing ground beef eliminates the primary source of saturated fat and dietary cholesterol in the original recipe. The black bean and mushroom swap introduces dietary fiber (~6g per serving), plant-based protein, and key micronutrients (iron, folate, potassium). Overall caloric load drops by ~90 calories per serving, and fat content is reduced by approximately 12g per serving, while carbohydrates increase only modestly due to the beans.

Cooking note: Ground round beef is replaced with a black bean & mushroom patty mixture. The blend uses finely chopped portobello mushrooms for umami depth and moisture, and canned black beans as a binder and protein source. Because this mixture is wetter and less cohesive than ground beef, a small amount of breadcrumbs is added to absorb excess moisture and help the patty hold its shape during the smashing step. The smashing technique still works, but slightly less pressing force is needed to avoid the patty crumbling apart. All other ingredients (sauce, tortilla, cheese, toppings) remain the same.
