Pre-Heat the oven to 200C/400F/Gas6
On a tray place the skinned mushrooms with stalks removed, season, pop in the oven for approx. 15 minutes
Take 2 of the skinned sausages and make into a round pat tie approx. 6cm across and 1cm deep - if you dampen your hands they will not stick as much - sprinkle both sides with the dried herbs and season
Spray a frying pan with fry light and fry your patties for approx. 3-4 minutes on each side, so they are lovely and golden and cooked all the way through!
After the mushrooms have been in the oven for approx. 10 minutes - pop a Cheese Slice on top of each mushroom and put back in the oven for 5 minutes to melt
In the meantime separate your Thin, add 2 teaspoons mayo to each piece, top with spinach and tomatoes
Remove the mushroom from the oven and place on top of the thins and then pop the cooked patties on top of that
