Not your ordinary sandwich, this gourmet sandwich is packed with flavor, texture and nutrients. It’s also super easy to make. Portobello mushroom caps can be a great meat alternative to give you the texture of meat. Although mushrooms are not protein rich, hummus does contain protein!
There are so many plant protein alternatives to be used, providing an array of vitamins, minerals, and fiber. The combination of both fiber and protein are essential to keep you feeling full and satisfied. Mushrooms also absorb flavors, extending their flavor. I marinated the mushrooms, peppers and onions for about 30 minutes while I worked out, but that is optional. If you’re on a time crunch, you can cook the veggies in the sauce instead.
