Since Halo Top launched in 2012, it's expanded from high-protein, low-cal ice cream to include pops, soft serve and now milkshakes!
Starting this month, people will be able to swing by Subway and grab a Halo Top milkshake.
This summer, the two brands teamed up to test out creamy Halo Top milkshakes at nearly 1,000 Subway locations in Colorado Springs, CO; Hartford, CT; Longview and Tyler, TX; Salt Lake City, UT; Toledo, OH; and West Palm Beach, FL.
Guests can choose from three classics: vanilla bean, chocolate, and strawberry.
Each milkshake has 350 calories or less and at least 20 grams of protein, plus 30 percent of the recommended daily value of calcium.
The shakes are being tested from July 22 through September 4.
