eaten in a day? I would say, for breakfast: coffee (that's a ritual) or hot chocolate with crakers or butter bread.
Lunch: Rice (white, yellow it doesn't matter) with beans, and meat (chicken, pork, beef ) if a Dominican doesn't eat rice dor lunch hasn't eaten.
and for dinner: mangu (smash plantains) with eggs, salchichon or fried cheese.
Of course it varies.
Typical meals: Sancocho, Locrio, asopao, mangu, ...... Dominicans a little help here speak up!
