Cheap Vietnamese food to bulk and gaining weight?

Been hitting the gym, I'm very light and wanting to gain weight. But searching on google only gives results suggesting cheap food from other countries but not really the case here. They suggested canned tuna, peanut butter. Peanut butter may be cheap in America but not really broke-college-students friendly here

What's cheap, native here and good for bulking? I mean, calories dense food. I have enough protein in my diet, just trying to hit my calories goal
