Peel the onion, cut in half and cut into fine strips. Wash the zucchini, quarter them lengthways, cut into small pieces. Clean, halve and slice the mushrooms. Chop the mint.
Heat a little oil in a large pan, add the onions, sauté until translucent. Add the meat and fry well. Deglaze with the Metaxa and allow to reduce for about 5 to 10 minutes.
Add the rest of the vegetables and garlic, pour a little water if necessary. Let simmer for about 5 minutes.
Add yogurt, tomato paste, oregano, cinnamon and feta. After the cheese has melted and mixed well with the rest, season with salt and pepper.
Mix in the mint at the very end.
Lightly toasted flatbread or rice goes well with it.
