Step 1 — Prep ingredients
Check your avocado is ripe before starting this recipe (see cooking tip). Preheat the grill to high. Finely chop the spring onion. Slice the tomato and avocado. Thinly slice the chorizo on an angle.
Step 2 — Cook chorizo
Put the chorizo in a cold medium frypan over medium-high heat and cook, turning, for 4-5 mins until golden. Remove the pan from the heat.
Step 3 — Prep bread rolls
Meanwhile, halve the bread rolls through the middle.
Step 4 — Toast rolls
Put the rolls on an oven tray, cut-side up, and grill for 2-3 mins until lightly toasted.
Step 5 — Flavour aioli
While the rolls are toasting, combine the aioli and spring onion in a bowl and season with salt and pepper.
Step 6 — Assemble and serve
Spread the rolls with the spring onion aioli. Divide the salad leaves, chorizo, avocado and tomato among the bases, then sandwich with the roll tops to serve.
