Begin by slicing your demi baguette in half lengthwise. Heat a cast iron skillet with 1 tbsp. olive oil over medium heat. Place bread on hot skillet, cut side down and allow to brown, about 3-4 minutes.
While your bread is toasting, prepare the rest of your sandwich toppings. I like to chop the giardineria up finely so that it really gets into the nooks and crannies of the crusty bread!
Remove grilled bread from skillet and spread pesto on to the cut side of the bottom of the loaf. Add giardineria and remaining toppings. Finish with the other browned piece of baguette and serve!
Notes
Want to make this into a turkey pesto grilled cheese? Simply follow the previous steps and finish it on a panini press for 3-4 minutes until the mozzarella cheese is melted!
