Cut the feta cheese into approximately 1 cm cubes. Cut the tomatoes into wedges of similar size. If necessary, pit the olives and ensure they are well drained. Wash and dry the basil leaves.
On each mini skewer, thread in this order: a tomato wedge, a cube of feta cheese, an olive, and a basil leaf. Ensure each item is centered on the skewer for aesthetic presentation.
Place one mini skewer in each shot glass. Ensure the skewers stand upright in the glasses and the ingredients are visible from the top of the glass.
Arrange the shot glasses on a serving tray or board. Serve immediately as an appetizer or hors d’oeuvre at your gatherings. The mini skewers can be enjoyed directly by hand or with a small fork.
