Sausage & Caramelised Onion Burgers

While the chips are baking, thinly slice the brown onion. Thinly slice the cucumber and apple.

In a medium frying pan, heat a drizzle of olive oil over a medium-high heat. Add the onion and cook, stirring regularly until softened, 5-6 minutes. Add 2 tbs of the balsamic vinegar, water and brown sugar and mix well. Cook until dark and sticky, 3-5 minutes.

While the onion is cooking, using damp hands, shape the pork sausage mince into burgers a little larger than your burger buns (one per person). In a large frying pan, heat a small drizzle of olive oil over a medium-high heat. Add the sausage burgers and press down with a spatula to flatten. Cook, turning occasionally, until browned and cooked through, 8-12 minutes. TIP: If your pan is getting crowded, cook in batches for best results!

While the burgers are cooking, place the bake-at-home burger buns on a wire rack in the oven until heated through, 3 minutes. In a medium bowl, combine the remaining 2 tsp of the balsamic vinegar, a drizzle of olive oil and a pinch of salt and pepper. Add the cucumber, apple and 1/2 the mixed salad leaves. Just before serving, toss to coat.
