"Best" as in highest calories per dollar. I am curious and so I compile the list from the Taco Bell website. Data is retrieved on April 21, 2021 from https://www.tacobell.com/food. I excluded items that vary in calories because of options, 0-calories items, and drinks. Some specific exclusions include "My cravings box" and party packs.
Sauces are on the top of the list. But assuming you are not buying $3 worth of Spicy Ranch Sauce and drink them for 2200 calories and receiving the gift of diarrhea, the best item is the Beef Burrito ($1 for 430 calories) from the value menu. The next two that follow closely are also from the value menu -- Beefy Potato-Rito and Cheesy Bean and Rice Burrito. The first non-value menu item at the top of the list is the Hash Brown Toasted Breakfast Burrito ($1.99 for 580 calories for 291.5 calories per dollar.)
For taste, I like the Beef Burrito and the Chicken Chipotle Melt (only $1 for 190 calories because ... chicken).
