Start off by making a pot of rice. Then take some frozen chicken burgers, which you might have in the freezer, and pop them into the oven. Now, peel and cut up some onions, carrots, and potatoes. Thought you had carrots and potatoes but can't find any? That's fine, just chop those onions. Great, now grab the Japanese curry roux cubes in your cupboard and open up half of it. Cool. Dissolve the curry roux into hot water and set aside. Your mise en place is done.
You can make your Japanese curry with just vegetables or you can add either cubed meat or ground meat. If you feel like adding meat, brown your meat in a pot with a bit of unflavoured oil. Add in your onions (and potatoes if you found some) into the pot before the meat is fully browned. Pour in the dissolved roux and bring to a simmer for about 10 minutes, stirring occasionally. Tidy up the mess you've made in the kitchen. Fluff the cooked rice. If you have carrots, add them into the pot of curry and cook until desired tenderness. The chicken burgers should be done. Take out the chicken burgers and slice. Now assemble and enjoy. That all made sense, right?
