cooking vegetables in same pan as a steak

So - if I log the steak I'm eating into myfitnesspal, but I cook the mushrooms and tomatoes in the same pan so they cook in the meat juices, do I need to increase the calorie count for the mushrooms and tomatoes? Or has that fat already been factored in with the meat? I mean - it should be part of the meat, right? Why should I have to pay for it twice! (cooking a Waitrose Aberdeen Angus Beef Rump Steak, 200 g, which I trim the fat off so it is just the lean rump, along with mushrooms and cherry tomatoes)

I should also say I've been doing this occasionally for the past 16 weeks and have still lost about 10kg, but interested in what other people recommend about logging veg in this way.
