If using wooden skewers, soak them in water for 20 to 30 minutes while preparing the chicken.

Finely chop 1/4 to 1/2 cup cilantro and grate 2 cloves garlic.

Juice 2 oranges and finely zest a small amount of orange peel.

Combine cilantro, garlic, orange juice, orange zest, brown sugar, avocado oil, white vinegar, and salt in the mixing bowl.

Whisk the sauce until the sugar is mostly dissolved, or blend it until smooth.

Cut 1.25 lb chicken thighs into bite-size pieces and place them in the mixing bowl.

Pour half of the cilantro orange sauce over the chicken and toss until coated.

Thread the chicken onto soaked skewers, or spread it in a single layer on a lined baking sheet.

Broil the chicken on high heat for 12 minutes until golden and cooked through.

Dice 1 cup mango and mix it with some reserved cilantro orange sauce to make an optional fruit salsa.

Brush the cooked chicken with remaining sauce and serve with the optional mango salsa.
