"This chain is bringing back the limited-time Quesalupa, a taco-inside-a-quesadilla hybrid, with early access for app users on March 10 and a full in-store rollout on March 11. The return leans on a reportedly clever method for getting cheese to melt quickly (possibly a cheese sauce), delivering the gooey, crisped-tortilla experience fans remember." - Jaya Saxena
