Make Sun-Dried Tomato Jam: Heat the grapeseed oil in a medium saucepan over medium heat. Add the sun-dried tomatoes and shallots, cooking until softened, about 4-6 minutes. Stir in the garlic and cook for an additional minute. Then, add honey, red wine vinegar, chicken broth, water, thyme, salt, and pepper. Bring the mixture to a boil, reduce the heat, and cover. Let it simmer for 30-35 minutes. While the jam simmers, prepare the whipped feta and toast the crostini to save time. Afterward, uncover and simmer for an additional 10 minutes, or until most of the liquid has thickened into a jam-like consistency. Remove from heat, transfer to a food processor, and pulse a few times until the mixture is slightly smoother. Set aside.
