Can I use chicken breast instead of thighs?
Chicken thighs caramelize better and stay juicy; breast will be drier. If using breast, reduce cooking time and don't overcook past 165°F.
What's a substitute for kecap manis?
Mix equal parts soy sauce and molasses, or use oyster sauce with a pinch of sugar. Kecap manis adds essential sweetness and depth; substitutes won't be identical.
Can I make this ahead?
Cook chicken and store separately up to 2 days; reheat gently before assembling. Toast bread and assemble fresh to keep it crispy.
How spicy is this sandwich?
Sambal oelek adds mild heat; adjust to taste or omit entirely. The peanut sauce balances any spice.
What bread works best?
A crusty, sturdy roll holds the moist fillings. Avoid soft white bread; ciabatta, Portuguese, or sub rolls work well.
