In a bowl mix 150 g cream, 50 g tahini (sesame paste), and the finely chopped tarragon. Salt, pepper and check the seasoning. Preheat the oven to 360°F (180°C).
2:
The tartines
Lightly toast 4 slices bread (in the toaster or under the grill), then lay them on a baking sheet.
3: Spread each slice with a generous layer of sesame cream.
4: Arrange the chicken, cut into small pieces, on top.
5: Finish with a little cheese, either sliced or grated.
6: Bake for 8 to 10 minutes.
7: Serve hot or warm.
Remarks
If you don't have tarragon, use a little parsley instead. For a different version, try mustard instead of sesame.
