Pit cherries by using a straw or pin to push out the pits. Alternatively, you can also pit the cherries by roughly cutting them around the pit.
Roughly chop onion and place in a food processor. Grind until fine pieces remain (if you don’t have a food processor, you can also grind the onion against a cheese or cheese grater).
Add olive oil to a large saucepan over medium high heat. Once oil is hot and has spread, add about ½ of onion (preserve the rest for the chicken burgers). Cook the onion, stirring occasionally, for about 4-5 minutes, until soft.
Add cherries, rosemary, salt and pepper to the pan and stir to combine. Cook for another 4-5 minutes, stirring occasionally, until cherries have softened.
Add water, balsamic vinegar, honey and stir. Bring to boil and then lower heat and let simmer for about 10-12 minutes, stirring occasionally, until the cherries have softened, and the mixture thickens.
Once done, pour into a jar and set aside.
Chicken Burgers (makes 6 burgers)
While cherry sauce is simmering, make chicken burgers.
In a large bowl, combine ground chicken, remaining ground onion, breadcrumbs, garlic, parsley, salt and pepper. Mix well to combine.
Using your hands, form mixture into 6 burgers and place on a plate.
Once cherry sauce is done and poured in a jar, add olive oil to the pan on medium high heat.
Add burgers (cook in batches if they all won’t fit at once) and cook for about 12-14 minutes, flipping once, until the internal temperature reaches 165 F.
Set aside on a plate.
Other
Add remaining 1 tablespoon of olive oil to the pan. Add kale and sauté for about 4-5 minutes, until soft and wilted. Set aside.
Roughly chop avocado and add to a bowl. Using a fork, mash avocado until almost smooth.
Toast whole wheat buns by placing face down on pan or in the toaster.
Assemble the burgers: top one half of bun with mashed avocado, sautéed kale, chicken burger and savory sweet cherry sauce.
