Thoroughly wash, clean and spin dry the lamb`s lettuce. Cut the onion into rings. Clean, halve or slice the mushrooms. Chop the peppers into cubes. Halve the cherry tomatoes.
For the dressing, mash the clove of garlic, stir together vinegar, mustard, salt, pepper (if possible black from the mill), sugar and lemon juice until the crystals have dissolved. Then whisk with the olive oil.
Arrange the salad on plates, drizzle with the dressing and sprinkle with crumbled feta.
I also added some basil and thyme as well as a few finely chopped black olives pickled in garlic and herbs.
Serve with baguette.
We eaten this salad with 2 people without bread (1 small portion was left over), were very full afterwards and were completely satisfied.
