I have beef tips thawed out and a marinade to go on them but now what else do i fix with them?

Well - depending on your marinade, white, yellow or brown rice goes well with beef tips. Serve with a fresh, steamed veggie - like asparagus (with a hollandais sauce), spinach (with a pinch or coarse ground sea salt) or cauliflower (with melted cheddar cheese) and hot rolls with a small pad of sweet cream er. Top off with a fruit type dessert like a home made peach cobbler and top that with vanilla ice cream or whipped topping!
