Soften the cream cheese for 10 minutes at room temperature.
In a medium bowl, combine cream cheese, cheddar, chopped onions, and diced peppers until well mixed.
Lay out half of the Ritz crackers and spread the mixture evenly on each one.
Top with another cracker and press gently to form a sandwich.
Chill for at least 30 minutes before serving to allow flavors to meld.
