Carefully peel the pineapple and slice it into 12 thin rings. Drain the tuna, crumble it into a bowl, and mix in the finely chopped chives.
Combine the mayonnaise, ketchup, and Tabasco. Pour this sauce over the tuna and stir until evenly coated.
On each of 4 serving plates, layer a pineapple slice with tuna mixture, top with a second slice and more mixture, then finish with a final pineapple slice.
Chill in the refrigerator until serving. This refreshing appetizer, inspired by classic French techniques, balances sweet pineapple with savory tuna for a tropical delight.
