  1. Step 1:

    Step 1

    How do you make Bonn weight-loss soup? Gather your ingredients. Wash and dry the vegetables first. Drain the green peas in a sieve to get rid of all the liquid. You can replace the bouillon cubes with a mix of salt and spices.

  2. Step 2:

    Step 2

    Peel the onion and cut it into thin half-rings.

  3. Step 3:

    Step 3

    Cut the tomatoes in half, remove the stem ends, and cut each half into medium pieces. You can use canned tomatoes instead — just choose ones with nothing but tomatoes in them. You can peel the tomatoes first if you like.

  4. Step 4:

    Step 4

    Finely shred the cabbage. Young cabbage is best — it's softer and juicier — but in winter or spring, before young cabbage hits the stores, any cabbage will do.

  5. Step 5:

    Step 5

    Peel the carrots and grate them on the coarse side of a box grater. You can also cut them into matchsticks or small cubes — they look even nicer in the soup that way.

  6. Step 6:

    Step 6

    For herbs, I used dill and parsley. Wash, dry, and chop them; trim the stems or leave them on, as you like. Core the bell peppers and cut them into strips. Green or yellow peppers make the soup more colorful.

  7. Step 7:

    Step 7

    Put a pot of water on the stove over medium heat and bring it to a boil. Add the vegetables — cabbage, carrots, tomatoes, onion, and peppers — and stir.

  8. Step 8:

    Step 11

    Cook the soup for 10 minutes over medium heat, then 5–10 minutes more over low. When the vegetables are tender, turn off the heat.

  • This recipe makes a big batch — enough for several days. Keep it in the fridge and reheat it before eating. You can have this soup whenever you want and as much as you want; there are no limits, since it's the foundation of the diet.
  • Important! Whether or not the recipe specifies an amount of water, it's always best to go by your own preference (do you like a thick soup or a thinner one?), the size of your pot, and the ingredients you're using. Keep in mind that the author has their own idea of how much of each ingredient belongs in the soup, and it may not match yours. In practice, if it's your first time making it, don't cook a whole pot at once. Make a small tasting batch for one or two people: scale all the ingredients down to 1–2 servings and figure the water at roughly 1 cup per serving for a very thick soup, up to 1½–2 cups for a thinner one. Remember that some of the liquid will boil off as it cooks. After tasting that small batch, you can adjust both the amount of liquid and the proportions to your taste. Before long, like most seasoned cooks, you'll be adding water and ingredients by eye.
  • An easy way to peel tomatoes: wash them and score a shallow X in the skin on top with a sharp knife. Drop them into boiling water for 1–2 minutes, then lift them out, let them cool a little, and slip off the skins.
