Fill and boil your kettle. Add the Spanish spice blend to a heatproof jug and crumble in the stock cube. Stir in 500ml boiling water to dissolve the stock cube. Set aside.

Peel and finely chop the onion. Halve the red pepper. Scoop out the seeds and white pith. Chop it to match the onion. Warm a deep frying pan over a medium heat and add the veg and 1 tbsp olive oil. Season with a pinch of salt and pepper. Gently cook for 10 mins, stirring once or twice, till the veg start to soften.

While the veg fry, dice the tomatoes. Peel and grate or crush the garlic. Finely chop the parsley leaves and stalks. Finely grate the zest from the lemon.

Stir the tomatoes, garlic, lemon zest and half the parsley into the veg. Cook and stir for 1 min, till the pan smells aromatic. Stir in the rice. Pour in the stock. Pop a lid on the pan, bring to the boil, then turn the heat right down and gently cook for 10 mins. Stir now and then to stop the rice sticking.

While the paella cooks, snap the woody ends off the asparagus spears, and chop the spears into chunks roughly 3cm long. Stir the asparagus into the paella and cook for another 10 mins, adding a splash more water if you think it’s getting too dry.

Halve the lemon and squeeze the juice from one half into the paella. Taste and add a pinch more salt or pepper if you think it needs it. Ladle the paella into warm bowls. Garnish with the remaining parsley and serve with the remaining lemon, sliced into wedges, for squeezing.
