A few steps in the making:
1) made a semi-enriched dough, scooped out the tomato innards, and made the mushroom-chicken stroganoff and let it cool a tad before stuffing it into the tomato
For reference, I did the stroganoff by sauteing some chopped onions in olive oil while boiling the sliced mushrooms in saltwater for about 5 minutes then straining them, then finely chopping a chicken breast, cooking that in with the onions, then adding a tidbit more olive oil, then flour, and stirring that till the flour is all mixed in and cooks for a bit, also adding some oregano and thyme, pepper and boullion for the salt, then slowly adding and stirring in some reduced-fat milk until it reaches a nice thick cream, then adding the mushrooms, and adjusting the creaminess to be the right final consistency. Turns out great each time :-)
