Balsamic Roasted Portobello Mushroom Burger w/ Tangy Slaw

Looking to become plant-based, but don’t know where to start? Embracing plant-based can be as easy as incorporating one plant-based meal into your day. A plant-based diet can help reduce your risk of a list of body ailments and increase your stamina, energy levels and metabolism. Start with replacing one meal a week with a plant-based dish. You will be amazed by how good you feel.

Listen, you do not have to be vegetarian or vegan to live a healthy life. In fact, both of those eating patterns take some work to ensure you are getting all of the nutrients you need (vegans have to be mindful of protein, vitamin B-12, iron, vitamin D, choline, zinc and calcium levels). It’s important to know, you don’t have to restrict what you love in order to be healthy.

We know many of you love meat and are not entirely wanting to give it up. If you love meat, then continue to eat what you enjoy. However, try to purchase wild-caught seafood, organic poultry and grass-fed beef. Animals fed more grains tend to have higher fat levels and reduce omega-3 content than some organic meat and poultry.

Mushrooms are known to be swapped out for steak and chicken because of the tender and moist texture. The Balsamic Portobello Mushroom Burger will have you shocked by how good the mushrooms taste. Start with this inspired mushroom burger and experience the multiple flavors of a plant-based burger.  It has a sweet and savory taste. The balsamic vinegar adds a velvety texture and explodes with tantalizing aromas. This vegan burger will leave you wanting more and is a great introduction to plant-based foods.
