Pluck the parsley or mint from the stems and cut finely. Cut the snow peas into bite-sized pieces, briefly blanch them with the peas in boiling salted water (max. 1 minute) and rinse with cold water. Put both well drained in a bowl and sprinkle with the parsley or mint. Grate and squeeze the lemon. Heat 50 ml of olive oil, add lemon zest and approx. 2-3 tablespoons of juice. Take off the stove. Whip the cream until it is semi-stiff, stir in carefully and season with salt, pepper and a pinch of sugar. Add the sauce to the vegetables and mix thoroughly with them. Let it steep for 20 minutes. Wash and dry the lettuce heart and cut into bite-sized pieces. Add to the sugar snap peas and peas salad and mix in.
Pepper the fish fillets lightly and wrap them in 2 slices of bacon each. Fry them in a little olive oil on each side for about 4 minutes at not too high a heat until crispy. Arrange the fried fish fillets with the salad.
