A reclosable, tamper-proof, fillable package includes a first side panel and a second side panel joined to each other along a pair of spaced side seals. A bottom wall extends between the first and second side panels with the bottom wall and the first and second side panels defining a package interior. A tamper-evident structure having opposite sides connected to each other extends above a combined zipper closure and slider device, and is connected to the zipper closure. Only one side of the tamper-evident structure is initially connected to one of the first and second side panels so that a fill opening adapted to receive a product is created between the other side of the tamper-evident structure and the other of the first and second side panels.
