Pat the chicken breast dry with a paper towel and cut into 1-inch uniform cubes.
In a small mixing bowl, whisk together the tamari, apple cider vinegar, half of the minced garlic, and the water to create the adobo marinade.
Heat 1 teaspoon of avocado oil in a medium skillet over medium-high heat and sear the chicken cubes until they are golden brown on all sides.
Pour the marinade mixture into the skillet with the chicken, adding the bay leaf and whole peppercorns.
Reduce the heat to low, cover, and simmer for 10 to 12 minutes until the chicken is cooked through and the sauce has reduced to a thick glaze.
While the chicken simmers, heat the remaining 1 teaspoon of avocado oil in a separate small pan over medium heat and sauté the remaining garlic until it is golden and highly fragrant.
Add the cooked jasmine rice to the pan with the toasted garlic, tossing constantly for 2 minutes to ensure the rice is evenly coated and hot.
Remove the bay leaf from the chicken and serve the adobo over the garlic rice, garnishing with freshly sliced green onions.
