Heat a nonstick skillet over medium heat; mist with cooking spray.
Add the sausage; cook, turning 2 or 3 times, until warmed through and browned, about 8 minutes.
Thread 1 small or 1/2 large basil leaf onto a small wooden skewer.
Add a piece of roasted red pepper, sun-dried tomato, mozzarella slice, artichoke, and sausage, arranging them on the skewer so that it can stand up on the sausage end.
Repeat with the remaining ingredients to make about two-dozen skewers.
