Wash the meat, dab dry and cut into strips. Heat oil in a pan. Fry the meat for about 2 minutes, turning it over. Peel and chop the garlic and add to the meat with curry paste.

Fold in the spinach, let it boil up for a short time, cover and let it simmer for 5-6 minutes on the switched off hotplate, season with salt and pepper.
