Toast the festive season with our Christmas cocktail ideas, including sloe gin fizz and spiced negronis
Heat the grill to medium. Spray the portobellos with a little oil on each side (keep the chopped stalks for later), season well and grill for 5 minutes on both sides until tender.
Heat another spray of oil in a frying pan and fry the onion until soft. Add the chopped mushrooms, plus the chopped portobello stalks, add a pinch of salt and fry until the mushrooms are lightly golden.
Add the garlic, smoked paprika and thyme for a minute, then stir in the breadcrumbs and walnuts for 1 minute.
Spoon the mix into the middles of the mushrooms and pack down to fill the cavities. Grill again, for another 5 minutes.
Serve with roasted vegetables or some greens.
