Cut the chilli lengthwise, remove the seeds and wash. Peel onion and garlic. Cut or chop everything into fine cubes and put them into the jar. Wash the fresh herbs, chop them finely or pluck the leaves from the thyme stalks, also in a glass. Add dried oregano, pepper flakes, lime juice and vinegar, stir vigorously. Spoon the olive oil by the spoonful into the preserving jar, shake vigorously in between while keeping it tightly closed.
Season to taste with salt and sugar. Keeps for several weeks in the refrigerator. Cover herbs with a layer of oil. The air seal prevents the sauce from going mouldy. The longer the Chimichurri can soak through, the better.
Grill the chops on each side for about 4 minutes, depending on taste, or fry them in some oil in a pan and season them.
