In a large skillet, heat 1 tbsp olive oil over medium-high heat
Add the chicken and cook for at least 10 minutes per side, flipping as needed to prevent sticking and burning
Remove the chicken from the pan
Add remaining 1 tbsp olive oil and sliced onion
Cover and cook for about 3-5 minutes, until the onion has softened
Pour in the white cooking wine and mustard then reduce to a simmer
Stir in the coconut cream and capers
Return the chicken to the pan, cover, and simmer until the chicken is cooked through, about another 10-20 minutes, depending on the thickness of the chicken
Serve chicken smothered in creamy mustard sauce and garnish with parsley if desired
