This is such an easy recipe that I am almost ashamed to talk about it, but it is something that my vegetarian husband enjoys while my daughter and I eat beef burgers.
Take one large portobello mushroom and coat it with olive oil, then McCormick Montreal Steak seasoning. Brown both sides in an oven safe fry pan, then place in a 350 Fahrenheit oven for 10 minutes.
Place on a bun and add the condiments of your choice.
Enjoy and God bless,
