A zesty new option is about to hit your local Jack in the Box for a limited time only. From April 22 to June 30, Jack in the Box is launching a new spicy chicken strips combo, and itâs gonna be caliente, baby. Youâll only get these spicy strips of chicken goodness for just over two months, so youâd better grab them before theyâre gone. The new spicy chicken strips combo will come in a three-piece or five-piece combo with small fries and a small drink, with pricing that will vary by market.
