Add the sweet potato to a large roasting tray with a good splash of olive oil
2 large sweet potatoes, cut into 2cm chunks

4
Cover the tray with tin foil and place in the oven for approximately 45 minutes until soft. Remove and allow to cool
5
Meanwhile, place a saucepan over a medium heat and add a dash of olive oil. Once hot, add the onions along with a pinch of salt and pepper.

Add the torn toast to the pan with the onions, stir to combine. Stir in the lemon zest and remove the pan from the heat

For the mushrooms, melt the butter in a pan over a medium heat. Add the mushrooms and garlic and cook until all the liquid from the mushrooms has cooked off and they are soft

3 garlic cloves, peeled
11
Squeeze in a little lemon juice. Remove the pan from the heat, pour the contents into a blender and blitz into a paste

1/2 tbsp of vegetable oil

Now assemble your Wellington. Roll out the puff pastry on a sheet of baking parchment until approximately 30cm x 40cm, then spread the mushroom mixture on top
500g of puff pastry
15
Toss together the spinach, sweet potato and onion-bread mixture. Spoon it in a thick line down the middle of the pastry, leaving a gap at either side so you can join up the edges of the Wellington
16
Hold one side of the baking parchment and lift it, with the pastry, towards the centre of the Wellington so the filling is half covered
17
Peel the baking parchment back, leaving the pastry in place, then repeat with the other side. The pastry should overlap in the middle
18
Beat the egg with the milk and brush it over the pastry to seal the join
1 egg
2 tbsp of milk
19
Fold up the ends so the filling doesn't leak out, then carefully roll the Wellington onto a baking sheet, with the seal underneath. Brush all over with the remainder of the egg mix

Bake for 45 minutes until puffed up, golden brown and hot through the middle

Meanwhile, peel the potatoes and place in a large pot. Cover with cold water and bring to a gentle boil. Cook for approximately 12-15 minutes or until tender
