Add the cider vinegar, adobo sauce, molasses, coriander and chipotle peppers and stir until incorporated. Stir in the chicken and thyme, season with salt and pepper, remove from the heat and set aside.
For the smashed white beans: Heat the olive oil in a saute pan over medium heat. Add the garlic and onions and cook until tender and translucent, about 5 minutes. Add the sage, stir to incorporate and add the white beans. Cook together until the beans are warmed. Remove from the heat and smash with a potato masher or fork. Season with chipotle chili powder, salt and pepper and set aside.
For the corn salsa: Preheat the grill to medium-high heat.
Place the corn on the grill and cook until the corn is tender and charred, 8 to10 minutes. Cut the kernels off the cobs and place in a bowl. Add the olive oil, jalapeno, red peppers, cucumber, cilantro and red onion. Season with salt and pepper, toss and set aside.

For the watermelon mint drink: Place 1/2 cup water and 1/2 cup sugar in a small pot, bring to a boil and remove from the heat. Add the mint to the pot, allow to sit and infuse syrup for about 15 minutes. Allow the syrup to cool. Strain and discard the mint. Place the mint syrup in the fridge until cold.
Place half the watermelon in a blender with the lime juice and simple syrup. Puree and pour over a fine strainer into a large pitcher. Repeat with the remaining chopped watermelon and place in the fridge until chilled.
Place the remaining 2 tablespoons sugar on a plate. Rim the tops of glasses with a lime wedge and press into the sugar to garnish. Place the ice cubes and watermelon mint drink in the glasses, garnish with lime quarters and enjoy!
