Mix olive oil with garlic powder, Italian seasoning, pepper and salt in a small bowl. Slice bread in 1″ pieces and slice tomato in 1/2″ pieces.
Coat both sides of the bread and tomato sliced with olive oil mixture using a brush.
Lay bread and tomato slices on baking sheet place in oven. Bake for 10 minutes and take bread out. Keep tomatoes in for 5 more minutes and let both sit.
While bread and tomatoes are roasting, use a cheese board or tray to lay out charcuterie: put burrata in the middle and slice with a butter knife a couple of times; roll prosciutto and put fruit and pistachios in bowl.
Surround burrata with plate of roasted tomatoes (best to serve with a fork) and bread.
