Preheat the oven to 200?C. TO PREPARE: BOEREWORS - Cook on the stove in a riffled cast iron pan until nicely marked on both sides. Transfer to the oven (pan and all) and bake for 15 minutes. BACON - Overlap the slices on a baking sheet and bake in the 200?C oven for ? 15 minutes until crispy. Remove and keep on paper towels until needed. BREAD - Preheat the oven to 200?C. Slice the breads in half lengthways, drizzle inside with olive oil and season lightly with Rosemary & Olive Seasoning. Bake for 5 minutes. AVOCADO - Pip, peel and mash avo lightly with Chilli & Garlic Seasoning and Lemon Vinaigrette. Cover. TO ASSEMBLE - Spread bread with avocado; slice the boerewors into 3mm slices and pack over avo. Cut bread into 5cm lengths on the diagonal. Top each one with bacon and onion rings. CHEF'S TIP: Cooking bacon and boerewors in the oven instead of on top of the stove prevents smoky fumes in your kitchen and simplifies the job for the cook.
