The quintessential Belgian coastal starter: ripe, hollowed beefsteak tomatoes filled to overflowing with fresh hand-peeled North Sea grey shrimp tossed in homemade mayonnaise.
Slice off the top cap of each tomato and reserve. Scoop out the seeds and inner pulp with a melon baller or spoon, lightly salt the inside, and invert on paper towels to drain for 10 minutes.
In a bowl, gently fold the delicate grey shrimp with the mayonnaise, lemon juice, and black pepper, keeping the tender shrimp intact.
Spoon the shrimp salad generously into each hollowed tomato until overflowing.
Place each stuffed tomato on a bed of crisp lettuce leaves, rest the tomato cap beside it, scatter with chopped chives, and serve with fresh Belgian frites.
