What protein options are typically available for Taco Bell's burritos?

The presence of beef, chicken, and beans as typical protein options for Taco Bell's burritos reflects the brand's focus on popular and widely accepted protein sources that align with their menu themes. Beef and chicken are the primary proteins found in many fast-food burritos, catering to customer preferences for traditional meat-based entrees. Beans, often used for vegetarian options or as a protein substitute, add variety and appeal to a broader audience, including those seeking plant-based choices. Taco Bell emphasizes these proteins in their burrito offerings to meet diverse dietary needs while maintaining flavor and texture, making this answer the most accurate representation of their menu.

The other options are less relevant to Taco Bell's offerings; fish and seafood, pork and lamb, as well as duck and tofu are not commonly featured in their burritos, reflecting a menu strategy that focuses on simpler, more conventional protein options.
