Place the chicken pieces in a large mixing bowl. Add the turmeric, cumin, garlic powder, salt, and black pepper and toss until the chicken is evenly coated.
Heat the olive oil in a skillet over medium-high heat until shimmering.
Add the seasoned chicken to the skillet in a single layer if possible and cook, stirring occasionally, for 7 to 10 minutes until the chicken is cooked through and no longer pink inside.
Taste the chicken and, if desired, sprinkle up to an additional 1/4 teaspoon turmeric to boost flavor and color; stir to combine.
Squeeze the lemon juice over the cooked chicken and stir to coat. Serve immediately sprinkled with chopped fresh cilantro.
