Am spending a month in Spain with my kid and my parents. Using a pressure cooker a lot right now as my mother and myself follow a low carb diet whilst my daughter and dad do not. Pressure cooking is great when you get back from the beach, by the time everyone else has washed off the sand and re-dressed I’ll have made the lunch (5 mins prep plus 35 mins cooking time).
The Italian chicken recipe is pretty similar to my own Spanish style staple chicken meal, but adding olives is really a step too far to me. We eat green and black olives with the accompanying salad, I just can’t bring myself to cook with them. Pre-prepared fried tomato is cheap and easy in this part of the world, as are decent stocks in tetra brick packets, all I need to add in addition to these are garlic, onions and other vegetables as well as chicken thighs, olive oil and a bit of wine. On the top, I’ll add a huge uncut potato which the carb eaters share between them.

I do miss one dish now that I’m low carb. If you aren’t and want a healthy and truly delicious taste of Spain, this may well be one of the loveliest things you can make in a pressure cooker. Have found this English version which covers the basics - Olla Gitana (it’s the pears that make this dish so extraordinary)
