Mix together flour, yeast, and salt. Stir in olive oil and water until a cohesive dough begins to form.
On a floured surface, knead dough until smooth, then place into a greased bowl and cover. Let rise until doubled, about 90 minutes.
Preheat oven to 375°F and line a baking sheet with parchment paper.
Place dough on floured surface and, using your knuckles, press down to deflate the dough and form a rough 10-inch circle.
Transfer dough to baking sheet, reform if needed, and scatter berries and goat cheese over the top.
Bake for 25-30 minutes. Drizzle with honey or balsamic vinegar before serving, if desired.
You may need more or less flour or water depending on the humidity of your home. Also, try swapping in 1/2 cup of whole wheat flour, but be sure to increase the amount of water (in small amounts) to adjust for the change.
