What was the total number of gross units opened by Taco Bell in the 2022-Q1 period 
 units opened outside of China, contributing to 5% unit growth in the rest of world year over year. Both KFC Division and Pizza Hut International delivered another exceptional development quarter with 587 and 283 gross units opened, respectively. While Yum China continues to be our lead developer, there were significant contributions from each of these brands in India, Asia, the Middle East and Latin America.
Taco Bell remains on track for another record development year with growth in next-gen assets in the U.S. and additional markets reaching scale internationally. On that front, we're excited to share that Yum China has committed to expanding the Taco Bell brand, which will allow even more people to live mas as we build our brand identity globally and grow our footprint in that market. To that end, we now expect to have three more markets to cross the critically important scale threshold of 100 units by the end of 2022, joining Spain, which reached that milestone in 2021.
The global development landscape is increasingly complex. But the sophistication, scale and capabilities of our teams and franchisees provide competitive advantages that allowed us to deliver yet another quarter of record unit openings. The visibility into our development pipeline remains strong. Now I'll discuss our Unmatched Operating Capability and the three key elements we're leaning into: Easy Experiences, Easy Operations and Easy Insights.
Before I provide an update across our Easy pillars, I want to comment briefly on our global supply chain. Our supply chain teams continued doing an amazing job building supply chain contingencies and acting as needed to secure product availability, including restaurant equipment, which is necessary for new store openings. Additionally, I'm proud of how our sourcing teams are leveraging our scale and cross-brand purchasing power to help our franchisees and equity stores manage costs in this highly inflationary environment as an important lever in maintaining long-term profitability. This scale combined with our operating experience and learnings from exposure to over 155 markets around the world create a unique competitive advantage for us as we navigate these inflationary pressures.
Starting with Easy Experiences. With continued reopening trends in markets around the globe, a frictionless experience remains front and center for the consumer. With that in mind, we are constantly adding new convenient ways for our customers to access our brands. KFC U.S.
and The Habit Burger Grill have made digital ordering even easier. Customers can now order via the app and pick up their food from a specific cubby or shelf within the restaurant. This enables a quicker and more seamless experience that eliminates the need to wait in line at the counter or in the drive-thru. Quick Pick-up is fully deployed across the KFC U.S.
system, and roughly one-thirds of the Habit stores currently have dedicated pickup shelves, with plans to expand more broadly in the coming months. In addition, Taco Bell U.S. recently launched a similar program in their equity stores and will continue to deploy it across their systems more broadly in the coming quarters. Both delivery and early tests of Quick Pick-up continue to free up drive-thru capacity for the Taco Bell system, which helped fuel their ninth consecutive quarter of average drive-thru times under four minutes, with a sequential improvement from their fourth quarter drive-thru speed.
Internationally, we have exciting projects in early stages, including our KFC Australia business, which is piloting a drone delivery program that gets our finger-licking good products to our customers' home or office in less than 15 minutes on average from when it's ordered. Next, I'll move on to Easy Operations, in which we are focused on streamlining operations for our team members and franchisees. We are installing a new kitchen display system and smart hub and leveraging our cloud-based point-of-sale system in our Taco Bell locations with the goal of modernizing the employee experience and providing more
