Perhaps your new favorite bean dish:
Bring the beans to a boil with enough water and simmer over medium heat with the lid on until tender.
Peel the garlic and press through a press, stir with wine, thyme leaves, vinegar, sugar, mustard, pepper and oil to make a vinaigrette.
Drain and cool the beans. Cut the tomatoes into eighths, cut the spring onions into rings and mix them with the beans into the vinaigrette. Season with salt if necessary: make sure that both the olives and the feta cheese are more or less salty! Finally, halve the olives and crumble the feta cheese. Put both on the lettuce.
