Drain the canned skipjack tuna thoroughly.

In a medium bowl, combine the tuna, olive oil, cumin, chili powder, garlic powder, oregano, and sea salt. Mix well.

Preheat a frying pan over medium heat for about 2 minutes, then reduce to low.

Carefully transfer the mixed tuna into the warm pan, spreading it out evenly. Cook for approximately 15 minutes, stirring occasionally.

Once cooked, remove from heat and serve immediately or transfer to an airtight container for leftovers.
