In a medium bowl, combine softened cream cheese, shredded cheddar, chopped green onions, and diced red bell pepper until evenly mixed.
Lay out half of the Ritz crackers on a clean surface and spread a layer of the cheese mixture on each.
Top with the remaining crackers to form sandwiches and press gently.
Arrange sandwiches on a platter and chill for 30 minutes before serving.
