Chop everything up! Start by chopping your charcuterie meats, cheeses, sun-dried tomatoes, Castelvetrano olives, cornichons, walnuts, and green apple into small, bite-sized pieces. You want everything roughly the same size so you get a little bit of everything in each bite!
Combine. Add the chopped meats, cheeses, and mix-ins to a large mixing bowl along with the freshly torn basil.
Make the dressing. In a small bowl, whisk together the olive oil, balsamic vinegar, coarse mustard, black pepper, and a pinch of salt. For a touch of sweetness, add a drizzle of honey. Fresh thyme is another delicious addition!
Toss it all together. Pour the dressing over the charcuterie mixture and gently toss until everything is evenly coated. Taste and adjust the seasoning as needed.
Jar it up! Divide the mixture evenly among three clean, 19-oz Weck jars. Seal and refrigerate until ready to serve.
Serve and enjoy! When you're ready for happy hour, either spoon the mixture into a cute serving bowl or serve it straight from the jars with cocktail picks! I love pairing this with crackers, crostini, or slices of toasted baguette.
