Blanch the green beans. Bring a large stockpot of water to a boil. Add the green beans and boil for 2 minutes or until bright green. Use a strainer or tongs to quickly transfer the green beans to a large bowl of ice water and submerge the green beans until completely chilled. Drain the ice water completely, then use a clean towel to lightly dry off the green beans.

Prep the honey garlic butter. Combine the butter, honey, rosemary and garlic powder in a small saucepan. Heat over medium heat until the butter and honey are completely melted, stirring frequently. Remove from heat and set aside.

Prep the oven and baking sheet. Heat the oven to 450°F (230°C). Mist a baking sheet with cooking spray.

Assemble the bundles. Using the same large mixing bowl, toss the green beans with 1/4 cup of the butter mixture until evenly combined. Portion the green beans into 8 equal-ish sized bundles (about 9 or 10 green beans per bundle), then gently wrap each bundle in a slice of prosciutto. Place the bundles evenly on the baking sheet. Brush with the remaining butter, then season with salt and black pepper.

Bake. Bake for 8 to 11 minutes, or until the prosciutto and green beans reach your desired level of crispiness.

Serve. Serve immediately, garnished with freshly-grated Parmesan cheese. Enjoy!
