6 hardboiled eggs, peeled
1 tablespoon minced scallion
1 tablespoon chopped fresh cilantro
1 small jalapeño pepper, finely chopped
1/4 cup mayonnaise
1 teaspoon prepared mustard
1/4 cup shredded Cheddar cheese
Cut a small slice from the tips at both ends of the eggs to create a flat surface for them to stand upon. Slice each egg in half crosswise.
Remove yolks; place in a small bowl and mash. Add scallion, cilantro, jalapeño pepper, mayonnaise, and mustard; blend well.
Spoon about 1 tablespoon of the yolk mixture into each egg half. Top each with cheese; sprinkle with chili powder.
Cover; store in the refrigerator.
Yields 12 appetizers.
