This croissant sandwich is perfect for breakfast or anytime of day.
Heat broiler. Spread 2 teaspoons butter on bottom half of each croissant; place buttered-side up on baking sheet. Broil 5 to 7 inches from heat until light golden brown (1 to 2 minutes).
Top each toasted croissant half with 1 slice cheese and 1/4 of ham. Continue broiling until cheese is melted (1 to 2 minutes).
Place 2 poached eggs and 1 slice cheese over ham on each croissant. Continue broiling until cheese is melted (1 minute). Sprinkle with chives; top each with remaining croissant half.
TIP:To poach eggs heat 1 1/2 to 2 inches water in saucepan to boiling. Reduce heat to low. Break egg into small bowl; carefully slip egg into water. Cook until whites and yolks are firm, not runny. Remove with slotted spoon.
