Wash the lettuce, drain it well and distribute it on the plates. Quarter or halve the cherry tomatoes, peel the cucumber and cut into small cubes. Cut the kumquats into fine rings while collecting the juice. Cut the spring onion into rings. Arrange everything over the salad.
Make a vinaigrette from olive oil, kumquat and lime juice and the spices and drizzle over the salad.
The cumin and the fine aroma of the kumquats give this salad an exotic note that goes well with Mediterranean and Middle Eastern menus.
