Brown the ground sausage in a large skillet over medium-high heat, breaking it into very small crumbles as it cooks. Drain the grease thoroughly and let the meat cool for a few minutes so it doesn't immediately liquefy the cheese.

In a medium bowl, combine the softened cream cheese, shredded white cheddar, garlic powder, and fresh chives. Stir in the cooled sausage until the mixture is uniform and thick.

Unroll the crescent dough and separate it into the pre-marked triangles. To make these "bite-sized" appetizers, use a pizza cutter to slice each triangle in half lengthwise, creating two skinny triangles.

Place a rounded tablespoon of the sausage mixture at the widest end of each dough strip. Roll the dough forward toward the point, pinching the sides slightly to keep the creamy filling from escaping during the bake.

Arrange the crescents on a parchment-lined baking sheet. Brush the top of each roll with the beaten egg wash—this acts as "glue" and creates a shiny, golden finish. Sprinkle the Everything Bagel Seasoning generously over the tops.

Bake at 375°F for 14–15 minutes. The rolls should be puffed and deep golden brown. Let them rest on the sheet for 5 minutes before serving; this allows the cheese filling to set so it doesn't run when you take a bite.
