Clean half of the soup greens and the onion, cut into small cubes and sweat in a little olive oil. Add water and lentils, salt and pepper. Add the chopped thyme. Bring everything to the boil and cook on a low heat for 30 minutes.
The lentils should have completely absorbed the water, otherwise they should drain on a sieve. Put in a bowl, mix in a dash of olive oil and balsamic vinegar, season with salt, pepper and sugar.
Clean and roughly dice the rest of the soup greens. Sweat in a little olive oil and pour in water approx. 2 cm high. Add salt, pepper, juniper berries and bay leaf and bring to the boil. Put in the cheek and let simmer for about 1 hour. Take out, season with salt and pepper.
Arrange the lentil salad on plates, cut the cheeks into slices and serve on top. Pour a little balsamic vinegar reduction.
