Nela Zisser is no stranger to massive food challenges: from eating a KFC family-size meal in 15 minutes, to a 6.7 lb vegan platter, and many more. This time, she returned to a classic challenge that she last completed in 2016: the 1KG burrito.In this challenge, she finished the gigantic burrito in under 100 seconds, marking a new personal best for the competitive eater. A supportive Mad Mex employee made a cheering gesture towards the camera midway through the challenge. Credit: Nela Zisser via Storyful
