I have eaten Sirena's sancocho for dinner every Sunday for ages. It is always crammed with meat, vegetables and root plants.
Which is entirely your choice, you opted in, most Dominicans doing it do it out necessity.
Guaranteed none of the folks in line left to pick up their Masserattis parked across the street in the baseman of the Blue Mall now, did they?
To say that Dominicans eat Platos del Dia because this is what they do culturally is insane, it's like trying to hide from the sun during the daylight or the moon in the evening.
