To make seasoned pretzels, start by placing pretzels in a large bowl. In a separate small bowl, mix ranch seasoning and garlic powder. Sprinkle the ranch mixture over the pretzels, but avoid stirring too much to prevent it from falling off.
Melt butter in the microwave and pour it over the pretzels. Toss to coat them with butter using a spatula. Microwave for 1 minute, stir, and microwave for 1 more minute, then toss again.
