In a large bowl, whisk together the yeast, water, and honey. Set aside for five minutes to proof, or until frothy.
Add in the almond flour, arrowroot flour, salt, egg, olive oil, and vinegar. Stir just until a dough forms.
Cover bowl with plastic wrap or a damp kitchen towel, and let rise in a warm spot in your kitchen for 30-60 minutes, or until the dough looks decidedly puffy and smells of yeast.
When rising time is nearly over, line a baking sheet with parchment paper or a silicone baking mat. Preheat oven to 400°F.
Transfer the dough to the prepared baking sheet and form into a round loaf. Use a sharp knife to cut diagonal lines every 1" along the loaf.
Bake for 20-25 minutes, or until the bread is golden brown on top. Remove from oven and let cool for 10 minutes, then slice and serve.
