Keep a taste of summer all winter long and #EatMoreWatermelon with these playful Watermelon Tropical Sushi—made with crisp, juicy watermelon and bright tropical flavors.
Watermelon doesn’t have to be just a summer memory. Thanks to year-round availability, you can enjoy fresh watermelon in creative ways anytime. These Watermelon Tropical Sushi rolls bring the sunny flavors of mango, pineapple and watermelon together for a refreshing appetizer or snack.
Even if winter weather arrives, watermelons are usually stocked in grocery stores in both mini and larger sizes. In colder regions local melons may be scarce, but many travel from warmer areas or across borders to reach grocery shelves. If you spot the mini variety, they make perfect single-serving fruit for recipes like these sushi rolls or for smoothies.
Watermelon is naturally pink from lycopene, mostly water (about 92%), and versatile in sweet and savory dishes. It’s low in calories, sodium, fat and cholesterol, and provides vitamins A and C as well as potassium. The rind and melon also contain citrulline, an amino acid that can support muscle recovery—making watermelon a great post-workout snack.
If you’re simply after delicious flavor, watermelon delivers there too. From cocktails and desserts to appetizers like these Watermelon Tropical Sushi, the melon pairs beautifully with tropical fruits and coconut. These rolls are colorful, easy to assemble, and perfect for entertaining during the holidays or any time you want a bright, healthy treat.
