Bole is simply roasted plantain and yam served with pepper sauce, or groundnuts as the case may be. In the Eastern and Southern parts of Nigeria, bole is served with pepper sauce, but in the Western part of Nigeria like Lagos bole is served with groundnuts. I believe you would find the bole very delicious.

Agege bread would do no wrong in your mouth as the butter melts pretty easily in your mouth while you toil with the sweet bread. Agege bread is usually very delicious and is eaten mostly as breakfast.
