For the lentil salad with blood oranges, boil the lentils in plenty of water until soft, drain and set aside. Peel the shallots and chop into small cubes. Remove the peel from the blood oranges and cut the flesh into finger-thick slices.
Remove the stalk from the lettuce leaves, wash well and pat dry. Cut the chives into coarse pieces.
Slowly sauté the shallots in 3 tablespoons of olive oil, add the lentils and deglaze with the vinegar. Season well with salt and pepper.
Mix the lettuce hearts with salt, pepper a tablespoon of olive oil and a tablespoon of vinegar.
Place the orange slices side by side, place the lettuce hearts on top and finally spread the lentils on top. Sprinkle the lentil salad with blood oranges with chives.
