Whisk the yeast with water, olive oil, maple syrup and sea salt in a bowl.
Add the spelt flour a little at a time and work to form a dough, and kneading it for about 5 minutes. Do not add more flour, the dough should be sticky.
Prover dough to double in size in a bowl covered with a tea towel, for about 40 minutes.
Preheat the oven to 250 degrees celsisus/485 Farenheit.
Pour the dough out onto a floured surface, knead it slightly and place on an oiled baking sheet with a little sea salt in the bottom.
Flatten the dough until it is about 1-2 cm thick and let rise until doubled in size, about 30 minutes. Put your fingers in the dough so that it formes a lot of holes, drizzle generously with olive oil and sprinkle with sea salt. Sprinkle with tomatoes and basil and push the whole tomatoes and basil leaves in the dough.
Bake the bread in middle of oven until golden brown, about 10 minutes. YUM!
