I actually add a lot more stuff than that, but that is a simple recipe.
If you want the simplest, just add some hot sauce to spice it up.
My complicated recipe without Ramen seasoning:
1. Fry onions with olive oil until near golden brown, then add garlic.
2. Add tomato paste (mixed with water),
3. Add more water (depends how much you are making), add more salt
4. Add your own mix of vegetables and beans. (I usually add celery, carrots, corn, peas, chili beans, and garbanzo beans) , boil until they are tender.
5. Add ramen noodles, boil on medium high.
6. In your bowl, add 2 spoonfuls of yogurt, a dash of dry mint, dil, parsley, a spoon of lemon juice, and your favored level of hot sauce, and/or sri racha sauce. Mix well, THEN pour soup in your bowl, mix well again. This soup will cure what ails you.
