Preheat the sandwich press (see Kitchen hacks). Cut the capsicum into 1.5cm-thick strips. Halve the buns.
Step 2 — Soften capsicum
Put the capsicum and 1 tbs water in a microwave-safe dish (see Kitchen hacks), cover and microwave for 5 mins or until softened.
Step 3 — Assemble panini
Spread the bun bases and tops with the barbecue sauce. Layer with the cheese, capsicum and one-third of the spinach. Sandwich with the bun tops.
Step 4 — Cook panini
Put the panini in the sandwich press, close and cook for 2-3 mins until golden and the cheese is melted. Cut the panini in half.
Step 5 — Make salad and serve up
Meanwhile, combine a drizzle of olive oil and a drizzle of white wine vinegar in a large bowl. Season with salt and pepper. Add the sunflower seeds and remaining spinach and toss to coat. Divide the panini among plates and serve with the spinach salad. Enjoy!
Step 6 — Kitchen hacks
Don't have a sandwich press? Put the assembled panini on an oven tray and bake in a 200C oven for 8-10 mins until golden and the cheese is melted. ~ Don't have a microwave? You can cook the capsicum on the sandwich press or in a frypan, turning occasionally, for 3-4 mins until charred.
