The flavors of the tropics are continuing to grow in popularity at restaurant chains — particularly tropical fruits, which seem to give guests a sense of adventure and novelty in the safe, generally sweet guise of fruit.

Although chain customers are being treated to a fair amount of coconut, mango and passion fruit, and even a little bit of guava here and there, pineapple remains one of the more popular tropical fruits on U.S. menus.

Rock Bottom Brewery recently introduced The Cabo Mahi, which is mahi mahi with smoked paprika ancho glaze topped with pineapple pico de gallo and served with red ale rice and Southwest Succotash.

Pineapple and fish also come together with P.F. Chang’s Grilled Pineapple-Citrus Swordfish, served with a mix of rice and summer vegetables and topped with daikon sprouts.

Pizza buffet chain Pizza Ranch recently used the fruit on two items. The Meaty Tahiti Pizza is made with ham, red onion, pineapple, red pepper, green onion, Cattleman’s Classic BBQ sauce and a mozzarella cheese blend. The Sweet Chili Pizza is topped with fajita chicken, red onion, green bell pepper and pineapple as well as the 175-unit chains’ original sauce and a sweet chile sauce.

Jamba Juice's Kona Berry Blast Smoothie is made with a beverage derived from dried coffee fruit and other juices. Pineapple and chicken come together in the Caribbean Tango, a dish at KFC’s new fast-casual concept, KFC eleven. The dish is made with the KFC’s new Original Recipe Boneless chicken, pineapple salsa, Cheddar cheese, black beans, tortilla strips, cilantro, pickled jalapeños and two types of barbecue sauce.

Charley’s Philly Steaks and sister chain Charley’s Grilled Subs also combine chicken and pineapple in their new Spicy Hawaiian Chicken Sandwich, introduced earlier this summer. It’s made with all-white-meat chicken, ham, Swiss cheese and the 500-unit chain’s signature Roasted Pineapple & Habanero sauce.

Pineapple can also be found in a lot of cocktails, particularly those made with rum. That includes The Melting Pot’s Sailor Chic, made with spiced rum, pineapple juice, orange juice and blackberry syrup, topped with club soda.

Many pineapple cocktails also include coconut, such as Red Robin’s Tropical Watermelon Punch, made with Malibu coconut rum and Grand Marnier shaken with muddled watermelon, citrus and pineapple juices, and grenadine. The drink is topped with shaved coconut and fresh watermelon.

Rosa Mexicano’s Papaya-Pineapple Punch is made with Mt. Gay rum and Cointreau, along with Cava and fresh papaya, pineapple, star fruit and lime. It’s served with coconut-water ice in a bowl that serves 4 to 6 people.

Bar Louie combines coconut rum, Midori, pineapple juice and fresh-cut pineapple in its Honeydew cocktail.

The classic pineapple-coconut cocktail is the Piña Colada, a frozen drink that combines those two fruits with the most tropical of spirits, rum. Three chains recently introduced virgin variations on that treat, starting with Pinkberry, which rolled out a Pineapple Coconut smoothie made with its new line of Greek yogurt.

Baskin-Robbins turned the Piña Colada into dessert as part of a new no-sugar-added lineup that includes coconut flavored ice cream studded with chunks of pineapple, and Jack in the Box added a Piña Colada Smoothie to its Real Fruit Smoothie lineup, which also includes strawberry, strawberry-banana, and another tropical flavor — mango.
