Prosciutto Sandwich with Burrata, Dressed Arugula, & Caramelized Onions

For caramelized onions: Thinly slice a whole onion. Add olive oil to a saute pan on medium heat and add your onions. Add salt + 1 tbsp butter and saute for 3 minutes. Turn heat to low, add 1 tbsp water, and continue stirring until caramelized and brown (about 10-15 minutes). Set aside.

For arugula: Toss arugula in olive oil, salt, pepper, and balsamic vinegar.

For sandwich assembly: Cut sourdough baguette in half and drizzle olive oil on both sides. Toast in oven or on stovetop. Place caramelized onions on the bottom half of the baguette, followed by prosciutto, 1 ball of burrata, and top with seasoned arugula. Close the top of the sandwich and enjoy!
