Preheat charcoal or gas grill to medium-high heat (about 350-375F).

On a flat surface, brush Portobello mushroom caps with olive oil and sprinkle with salt both sides.

Grill, for 3-4 minutes per side. Remove from grill and assemble burger, spreading Avocado ranch on both the bottom and top buns, layering lettuce, grilled Portobello, avocado slices, salsa, and additional avocado ranch dressing.

*if you can’t find bean and corn salsa, mix salsa with corn kernels (frozen or canned) and cooked black beans to your desired consistency.
