Split pea soup (erwtensoep)
A winter classic: thick green split pea soup with pork and smoked sausage.
Well-cooked hot dish

Ingredients
- green split peas
- celeriac
- leek
- carrot
- potato
- onion
- pork
- smoked sausage (rookworst)
- salt
How it is prepared
The peas simmer with meat and vegetables for hours; the sausage is added at the end and heated through.
Food safety with low immunity
- Cook meat right through: steaming hot inside, with no pink parts or pink juices.
- Avoid dry-cured or cold-smoked sausage and ham with low immunity, or heat them in the dish until steaming.
How to prepare it during treatment
Heat the sausage in the soup until steaming. If you do not eat pork, it can be made with beef or turkey sausage.
Your diet during treatment is agreed with your doctor. Sample 7-day menu for the treatment period →
Storage
Cool quickly (within 2 hours), refrigerate in shallow containers and eat within 1–2 days; with low counts many teams advise 24 hours. You can freeze portions.
Reheating
Reheat only once — bring to the boil, stirring. It should be steaming hot, not just warm.
Symptoms it may suit
- Constipation. Fibre (pulses, vegetables, grains) may help with constipation — together with enough fluids.
- Low appetite. Gives a lot of energy and protein in a small portion — can help when appetite is low.
- Weight loss. Energy-dense and easy to enrich (oil, cheese, yoghurt) — can help with weight loss.
These are general observations: what suits you can change from day to day.
