1. 1. Heat a medium sized saucepan with 1 tablespoon of olive oil to medium, hot and saute the onions for 5 minutes until softened. Add a pinch of salt, good dose of black pepper, turmeric and stir.
2. Meanwhile also heat a frying pan to medium heat with a tablespoon of olive oil and pan fry the herbs for 5 minutes. Stir regularly.
3. To the softened onions add the stock, chickpeas, fried herbs, soaked saffron and bring to the boil. Reduce to a simmer then add the juice of 1 lime and the rhubarb, cover and simmer for 10 minutes. Add the chard and cook for a further 2 minutes.
4. By now the rhubarb should be softened, yet not mushy or stringy. Taste and if too sour add a teaspoon or two of maple syrup or honey to sweeten. Also add more salt and pepper if required and another juice of half a lime to brighten it, reserving the rest as slices or wedged as a garnish.
5. Pile up the stew into a serving bowl or take the saucepan straight to the table. Garnish with some extra herbs.
