Cut the tenderloin into 1.5 cm thick medallions. Season them with salt and pepper.
Mix the tomato purée, Chipotle paste, olive oil and the spices together. Add the squeezed juice of ½ lime.
Coat the medallions with the paste and put them in a shallow dish.
Marinade for minimum 1 hour, preferably overnight.
Transfer the medallions into a baking tray and pour over the marinade. Bake in a preheated oven, preset to 180°C , for about 25 minutes.
Alternatively, griddle, grill or barbecue them for about 3 minutes on each side.
Serve with chopped fresh herbs scattered on top and lime wedges on the side.
