They may do. Buddhists vary widely in the diets they adopt. While monks and nuns are usually vegetarian, or even vegan, there is no reason why they can't have vegetarian Pizza. Other followers of the faith have much wider diets, including meat, so I'm sure many of them enjoy pizza.
Lay Buddhists can eat whenever they want. Buddhist Monks and Nuns typically do not eat after noon.
Most vegetarian Buddhists eat rice. Basically what other vegetarians eat. Some Buddhists do not eat onions or garlic.
they eat food
yes
She DOESN'T eat pizza. An easy way to check your choice is to remove the contraction. You would not say "she do not eat pizza," so you wouldn't say, "she don't eat pizza." On the other hand, "she does not eat pizza" indicates that "doesn't" is the right choice.
Depends on the Buddhist.
they eat mostly Pizza
All Buddhists do not eat lamb. All of any group do not act the same way. Some Buddhists are vegetarian, some have more omnivorous diets. The only restraint is that a Buddhist should not specifically require an animal be killed for him to eat.
Because when you eat meat you kill a animal to eat it and they don't want to kill so that's why Buddhists don't eat meat.
Buddhism has no rules so Buddhists may eat any food. Monks would be likely to eat less meat but will eat anything offered to them. The Buddha taught of UPAYA KAUSALA (skillful means) which basically means that Buddhists should decide for themselves in accordance with the siuation, what to do e.g. in Tibet, where vegetables are hard to grow, monks happily eat meat.
Some of the dietary restrictions for Buddhists include meat and fish. Some Buddhists also do not eat leeks, onions, and garlic.
"Did he eat pizza?" is the past tense.
