Wash the tomatoes, quarter them, remove the seeds and cut the flesh into small cubes. Clean, wash and finely chop the spring onions. Peel garlic and press it through a garlic press. Mix yoghurt, garlic, lemon juice and zest. Stir in tomatoes and spring onions and season with salt and pepper.
Wash the chicken filet, dab dry and cut into 12 small cubes. Halve the bacon slices and wrap half a slice around each meat cube. Heat oil in a pan and fry the chicken cubes for 4-5 minutes, turning them over. Season the meat with pepper (no salt is necessary). Arrange the chicken cubes with some sauce on the spoons and serve
