Make the Homemade Aioli: Smash cloves of garlic with the back of a knife on a cutting board until you have a paste. Add dash of salt. In a small bowl, add egg yolk, fresh lemon juice and Dijon mustard. Whisk to combine. In a measuring cup, combine extra virgin olive oil and vegetable oil. Slowly add oils to yolk mixture, whisking constantly. If the oil starts to separate, stop adding oil and whisk until all oil is mixed in and continue with remaining oil. Add the garlic paste. Chill until ready to use. Makes 1/2 cup aioli.

Assemble the sandwich: Spread one slice of focaccia bread with the aioli. Top with Swiss cheese, spring greens and smoked ham. Heat grill to high heat. Cut each peach in half and remove the pit. Brush all sides with canola or vegetable oil. Place on grill, cut side down and grill for 2-3 minutes. Remove from grill and slice thin for sandwiches. Finish by adding grilled peach slices to each sandwich.
