I found it in my new cookbook - fruits sweet and savoury.
When you have semi black bananas, you only need 10 minutes in the oven. Less ripe ones need a bit more time.
recipe:
2 bananas
1/2 lemon
4 tsp olive oil
1 tsp honey
1 vanilla pod
Preheat the oven 190 C fan.
Split the vanilla pod lengthwise in half, cut it into 4 cm sticks.
Try to find the most straight parts of the bananas.
Cut it into 5 cm pieces - leave the skin on !
Prick the banana in the middle with a toothpick, insert a piece of vanilla pod.
Mix olive oil, honey and lemon juice.
Use an ovenproof dish.
Bake for 10 - 15 minutes.
Pour some of the juice back over the bananas when serving.
