This is a simple roast with mushrooms and garlic that I did on my Weber bbq.

Ingredients:
Roast beef
mushrooms
garlic
oil
can of beer
Himalayan Salt & ffreshly ground black pepper
bbq sauce
Honey garlic & serrano pepper & lime

Method:
Pre heat your bbq to 250 degrees then add your roast using the indirect cooking method *the heat is on one side of the bbq and your meat is on the other side.* drizzle both kinds of bbq sauce over the roast and let it cook. I like to rotate the meat and drizzle the bbq sauce over the meat ever so offin (more accurately every 2 beer's ) once the roast is almost done get out a cast-iron pan and add some oil and add the roast and the mushrooms and garlic around the roast and set back on the bbq. Once the mushrooms are about half way done add a cam of beer and let it cook until the garlic is nice and soft and the mushrooms are done. once every this is ready add salt and pepper to your likeing.
