According to Quintell, if one is interested in a Taco Bell Rotel, they should order a Nacho Bell Grande with chips on the side. This should include meat, cheese, sour cream, and tomatoes.
Just add your desired items totaling $20, then include an order of Nachos Bell Grande, and it will become free once you hit the $20 total (before tax). Uber Eats users aren’t left out of the fun.
