On sauteeing or cooking mushrooms, buttons will need little or no slicing, portabella I like thick not real thin, more flavorful, same with full flavor shiitake.
Maybe 1/4", 3/8" more, or how you like them.
Some recipes have fewer ingredents but to me less flavor. Some actually use bone marrow and/or homemade beef broth, it's all up to you. Canned beef broth (like chicken broth) is fine out of a can or box. 10 oz, 12 oz, whatever you have is good.
Like garlic? Hey it's good for you, none, 1 smashed clove, two+ it's up to you.
Red wine, generally something you would drink at lunch/dinner.
Bon appetit.
