First, slice all veggies and place them in a large bowl. Meanwhile, soak skewers in water for 30 minutes to prevent burning while grilling.
Dump all sliced veggies in a freezer bag.
In a small mixing bowl combine oil, lemon juice, dijon mustard, honey, garlic, basil, oregano, parsley, salt, and pepper. Whisk to combine.
Pour marinade into freezer bag and seal. Using your hands toss around to coat veggies. Place in fridge for at least 1 hour to marinade.
Remove from fridge and thread onto skewers until all veggies are used.
Preheat grill to medium heat and grill skewers for 10 to 12 minutes or until cooked through and tender.
