Boil the potatoes in salty water (1 tsp salt should be fine) until soft. If the skin looks good, leave it on.
In the meantime, cut the bell pepper, mushrooms and zucchini into equal size small chunks.
Thinly slice the red onion. When the potatoes are soft (poke with a knife to check), drain them.
Heat up a big frying pan, cut the potatoes into quarters and fry them on medium heat until browned. When they’re almost done, add the paprika/mushrooms/zucchini and fry it all together. Depending on the size you’ve cut the veggies, this will take about 5-6 minutes.
When everything is ready, throw in the raw red onion and the spinach, season with salt and pepper and enjoy.
Jansen’s pro tip
Boil the potatoes the night before! Not only do they fry from cold really well, you’ll make lunch super-quick! If you don’t like raw red onion, throw it in when you fry the rest of the vegetables.
