When using dried brown beans, start by cooking the beans for about 30 minutes. Then add the potatoes, sundried tomatoes, and onions. Cook for another 20 minutes.
Time to add the carrot slices and apple! Let everything cook for another 10 minutes. *In case you are using precooked beans, you can add these the last few minutes of the cooking time. These just need to be warmed up ;)
In the meantime, you can mix the cornstarch with a few tablespoons of water. Mix this until all the lumps are out.
Then, take about 400 ml of the cooking liquid. Transfer this to your frying pan, whereafter you add the mixed cornstarch water. Bring this, while stirring, to a boil.
Once all the ingredients are cooked, you can drain these. Add the cooked ingredients to your frying pan and cover them all with a nice layer of light gravy.
