vegetarian torta made with bolillos and roasted poblanos and portobello mushrooms with guacamole and cheese  

Guys, tell me it isn’t so, but my daughter has become a vegetarian. My girl was once upon a time, a proud carnivore and could put down a burger or steak like a champ.

Now, she is leaning towards veggies instead. She has actually been a great example for all of us, and taught us to eat more veggies, which is always a good thing (ok, Martha Stewart).

In my effort to cook more plant-based meals I came up with this delicious sandwich. Initially, I wanted to serve these on focaccia bread, but can never resist freshly baked bolillos at the bakery.

This is a simple sandwich that is honestly so easy to make and oh so satisfying. It’s a bolillo loaded with mashed avocado, tomato slices, a grilled portobello mushrooms, mozzarella cheese, and topped with a roasted poblano pepper giving it the perfect amount of spice.

If you are dabbling in a plant-based diet, mushrooms are very hearty and when grilled are very satisfying. I promise, you won’t miss the beef when you eat this meal.
