In a large mixing bowl, place the softened cream cheese, sour cream, onion powder, garlic powder, and Worcestershire sauce. Use a hand mixer on medium speed for about 2-3 minutes until the mixture is smooth and well combined.

Once your creamy base is ready, gently stir in the chopped green onions and shredded cheddar cheese using a spatula. Mix until the ingredients are evenly distributed, about a minute.

Carefully fold in the chopped deli meats—ham, turkey, and roast beef—into the creamy mixture without overmixing for about 2 minutes.

Transfer the mixture into a serving bowl or an airtight container, cover it, and place in the refrigerator for at least 1 hour.

After chilling, serve Iowa Party Bites with assorted crackers, scooping out generous portions onto each cracker.
