Quarter the baguette and cut lengthwise. Cover the lower baguette pieces with ham, pineapple, tomato slices and cheese. Place the topped and unpadded baguette pieces on a baking tray lined with baking paper.
Melt the cheese under the preheated grill for about 5 minutes (under observation). Take it out and let it cool down a little. Spread some dip on unfilled baguette pieces and place on the filled baguette pieces.
