A stack of three cans of Tuny tuna.

The video opens with a stack of three cans of Tuny tuna. The scene then transitions to a person adding ingredients to a bowl: first, canned tuna, then diced white vegetables (likely jicama or potato), followed by diced cucumber, diced carrots, diced red onion, and finally chopped cilantro and jalapeño. The ingredients are mixed together with a spoon. The mixture is then spooned onto a tostada and topped with avocado slices. The final shot shows the finished tostada with avocado, with the Tuny cans and other ingredients in the background. The text 'Lo tuyo es Tuny' appears at the end.
