Preheat oven to 350ºF.
Slice a loaf of French bread in half. Place the bread, cut side up, on a large baking sheet lined with parchment paper.
Brush the cut sides of French bread with ranch dressing. Add bacon crumbles, diced fresh tomatoes, feta cheese, and mozzarella cheese. Sprinkle with garlic powder.
Bake for 15-20 minutes, until the cheese has melted. Garnish with green onions and cut into slices.
