I loooooove beans with my arepa, black, red, white beans you name them, I love them lol. But to be completely honest, my favorite arepa contains cheese and fried plantains -drools-.
I also love tomatoes, onion and cheese. I understand your search for new tastes, I do the same once a month, because I get super bored eating the same ol' arepa with cheese everyday.
I need variety in my life hahahah
:) ¿Cada cuánto te las comes con tajaditas fritas? Generalmente me despierto después de que hacen las arepas y no me da tiempo de preparar nada. D:
