Preheat the oven to 180 °C (350 °F) convection/fan.
Wash 4 large sweet potatoes thoroughly and pat dry.
Crush
1 tsp fennel seeds and
1 tsp coriander seeds in a
mortar and mix with
3 tbsp olive oil.
Brush the sweet potatoes with the spiced oil, place them on a baking sheet (lined with parchment paper if you like) and put them in the hot oven for about 40 - 45 min.
Meanwhile, halve the 3 red onions and cut them into strips. Trim 2 scallions and cut them into pieces about 3 cm long.
Heat a little olive oil in a small pan and slowly braise the prepared red onions over medium heat until soft.
At the same time, cut the 1 eggplant into slices about 1 cm thick, salt lightly and let them sit briefly on a paper towel.
Cut the 1 zucchini into cubes of about 1cm.
Halve the 1 chili pepper, remove the seeds and cut it into thin rings (it's best to test the heat first so it doesn't end up too spicy).
Finely dice the 2 small garlic cloves.
Pat the moisture off the eggplant slices and dice them small as well.
Heat plenty of olive oil in a pan and fry the diced eggplant and zucchini, the garlic and the fresh chili over high heat.
When the eggplant and zucchini are done, season the cubes with salt, pepper and a pinch of pimentón and keep them warm.
Add the prepared scallions to the onions, which have softened in the meantime, turn up the heat and fry briefly. Add 2 tbsp agave syrup or honey and 0.25 tsp salt and caramelize the onions for about 1 min. Turn the heat down and keep the onions warm.
In another pan, fry 500 g mixed ground beef and pork with a little olive oil until crumbly and season with the spices plus salt and pepper to taste.
Crumble 200 g feta a little and set it out in a bowl.
Pick the leaves from 4 sprigs cilantro and chop them coarsely.
To serve, carefully cut the finished sweet potatoes open in the middle and pull them apart slightly. Top with the ground meat, the eggplant and zucchini, some crumbled feta, the caramelized onions and cilantro.
