Dice the onion and chicken breast. Put the onions in the pan in a little oil and let them turn translucent.
In the meantime, dice all the vegetables and the banana and mix well in a bowl.
Also put the chicken in the pan and fry briefly. Add the vegetables and after frying them briefly, deglaze with the coconut milk, simmer a little over a low heat.
Chop 3 chiles and cook with them. The dish is ready when the pepper pieces start to soften. Season with curry (a lot!) And salt and serve.
