On Day 6, beef and tomato only, can onions be eaten with the tomato? (I made a home-made tomato sauce with tomato, spices, garlic and onion to eat with my meatballs, and then I made a tomato/onion salad, and finally I sauteed onion to eat with my steak - no oil - water only). Also, what about mustard? Just a teeny-tiny amount on the burger? Trying so hard to stick to the menu, but also be creative so that I will WANT to do this again. THANKS
