Bring 3 inches (7.5 cm) of water to a boil in a saucepan. Reduce to a gentle simmer. Break one egg into a small dish. Gently slip egg into water. Repeat process with second egg. Cook in barely simmering water for 3 to 5 minutes or until cooked as desired.
Meanwhile, divide salad leaves between two plates. Arrange croutons over leaves. Heat oil in a small fry pan; add garlic and sauté for 1 minute. Add vinegar and heat through for about 30 seconds.
Remove eggs one at a time with a slotted spoon. Place a poached egg on each salad. Pour warm dressing over each one. Scatter with feta cheese and a little black pepper, if desired.
