Follow these simple steps to create your amazing Tomato Focaccia Rolls:

1. Activate Yeast: In a small bowl, combine the warm water, sugar, and yeast. Let it sit for about 5-10 minutes until frothy.
2. Mix Dry Ingredients: In a large mixing bowl, sift together the flour, salt, and garlic powder.
3. Combine Mixtures: Make a well in the center of the dry ingredients. Add the yeast mixture and olive oil into the well.
4. Knead the Dough: Mix until a dough forms. Transfer to a floured surface and knead for about 8-10 minutes until smooth and elastic.
5. First Rise: Place the dough in a lightly oiled bowl, cover it with a damp cloth, and let it rise for about 1 hour or until doubled in size.
6. Shape the Rolls: After rising, punch down the dough and gently knead it. Divide into 12 equal pieces and shape each into a roll.
7. Prepare Baking Sheet: Arrange the rolls on a parchment-lined baking sheet, leaving space between each one.
8. Add Toppings: Press halved cherry tomatoes and sprinkle chopped rosemary on top of the rolls, followed by a drizzle of olive oil.
9. Second Rise: Cover the rolls with a cloth and let them rise again for about 30 minutes.
10. Preheat Oven: Preheat your oven to 400°F (200°C).
11. Final Bake: Sprinkle flaky sea salt over the rolls and bake for 25-30 minutes, or until golden brown.
12. Cool and Serve: Allow to cool slightly on a wire rack before serving warm.

These straightforward steps will guide you to create perfectly fluffy Tomato Focaccia Rolls that are bursting with flavor.
