I couldn't remember if the seeds were edible or not and I wasn't

Along our journey on a Saturday when there were lots of locals out enjoying the beaches and the surf, we happened upon a roadside stand selling pickled mango. Sounded interesting. We stopped. The gal gave us several different samples of mango as well as sweet Hawaiian onion and we decided on the sweet/tart pick

Here's a recipe I found for them. They look easy enough to make but there is a special Hawaiian sea salt that has a pink color. And you have to be careful that you don't get the mangoes in the store that are too soft.
Pickled Mango
3 cups green mango slices
1 cup rice vinegar
2 cups granulated sugar
1/4 cup Hawaiian salt
Place mango slices in a clean glass jar. Combine vinegar, sugar and salt in a non-reactive saucepan and bring to a boil. When sugar and salt are dissolved, remove from heat and cool to lukewarm. Pour over mangoes. Cover and let stand for 24 hours, then store in refrigerator
Each weekend on a beach we passed to get to church, we saw a homemade sign next to a large grill that said, "Huli Huli Chicken". A group of people cooked and sold this wonderful offering each weekend. We got there too late on a Saturday when they sold out, but managed to connect the next day on the way back from church. And were we glad we did! It was delicious. We got a large size plate (actually a carry out plastic box) and split the meal that included rice and sweet corn.
[I apologize for the sideways picture. It came from my iPhone and I can't get it to stay in the right position when it posts.]

Curious to what Huli Huli meant, we did some Internet research and discovered that Huli Huli is the name of the BBQ sauce. Apparently it's named that because huli was the word that Hawaiians used to indicate that the meat/poultry on the grill needed to be turned. It is quite popular and the site where I found it for sale says that there are lots of roadside stands that use it for weekend BBQs.
So there you have it. Some Hawaiian flavors available most any place you live--thanks to the Internet and delivery companies.
