Got this from Sophie Grigson’s show, but substituted some ingredients.
2 Tbsp. Butter
2 Tbsp. olive oil
2 slices bacon (thinly sliced)
2 slices ham (thinly slized)
200 g mushrooms (thinly slized)
1 pc. white onion (thinly slized)
200 g. flamengo cheese (grated)
100 g. parmesan cheese (grated)
salt & pepper to taste
Preheat oven into 180 degrees C. Separate egg white from yolk and set aside.Heat olive oil and butter in a pan, add bacon & ham and fry just quickly until done. Remove from pan. With the same pan (with the remaining oil & butter used with frying the bacon, this really adds flavor) add mushrooms and continue frying, add onions and stir-fry until mushrooms turn golden brown at the sides. Add the cooked bacon & ham stir and remove from heat and set aside.Add the yolks into the cooked ingredients, season with salt & pepper and set aside.Beat egg whites with an electric beater until stiff. Slowly fold-in the yolk mixture into the stiffly beaten eggwhite. Return the whole mixture into the pan, continue cooking with low fire. Remove from fire and bake for 5 minutes or until cheese melts. Serve immediately with toasted bread.
Note: Make sure to use oven proof handle of your pan otherwise, transfer the whole mixture to an oven-proof dish before putting it in the oven.
