Next, heat oil in a pan and stir-fry meat and onion until onions are lightly browned. Put the cooked meat and vegetables (carrots, potatoes) in a large pot, add water and bring to boil. After a few minutes, reduce heat and simmer until meat is tender. Finally, add curry powder and stir. Let it simmer for 5 minutes then serve.
英語では「野菜を一口大に切る」とはあまり言わず”Cut”や"Prepare" で済ますことが多いのですが、もしどうしても言いたいなら、”Cut veges (ingredients) into bite-size. " となります。また、焦げ付かないよう混ぜながら炒めるのは”Stir-fry”と言います。
