I think a beach picnic, even a picnic with “just” sandwiches, should be more memorable—and delicious—than everyday picnic fare, especially since boneless ready-to-serve hams are so readily available. Purchase deli-sliced Havarti and brioche or batards for the sandwich bread. The Peach-Mustard Spread makes 2 cups. You can refrigerate leftovers for up to two weeks.
For the sandwiches:
1 boneless sliced heat-and-serve ham quarter
2 large navel oranges
1 (12-oz.) can cola
½ cup firmly packed dark brown sugar
1 tsp. ground cloves
6 French or crusty bread rolls, halved horizontally
1 lb. sliced Havarti cheese
1 (5-oz.) package baby arugula
For the peach-mustard spread:
1 cup peach preserves
1 cup grainy mustard
1. Preheat the oven to 325°F. Place the ham in a baking dish.
2. Slice 1 orange and place the slices between the ham slices and over the ham.
3. Grate the zest and squeeze the juice from the remaining orange into a bowl and add the cola, brown sugar, and cloves. Pour over the ham. Bake for 30 to 35 minutes, or until the ham is browned. Let cool.
4. To make the spread, stir the preserves and mustard together in a small bowl. Spoon a little onto the cut sides of each roll. Top evenly with ham slices, cheese slices, and arugula. Serve.
