Combine the chicken, garlic, olive oil, adobo sauce, and seasonings in a large bowl or ziplock bag. Cover with plastic wrap and refrigerate for at least 30 minutes, or up to 2 days.
Preheat about 1 tablespoon of olive oil in a large pan over medium-high heat.
Add the marinated chicken to the pan and cook, turning occasionally, until completely cooked through, about 6 to 7 minutes per side.
Remove the chicken onto a large cutting board and allow to rest for at least 5 to 10 minutes, then slice or chop.
Serve in a burrito, in a salad, or on its own!
