Place the roasted capsicum/red peppers, sun dried tomatoes, cashews, oil, garlic, lime juice and brown sugar in a food processor and pulse until blended (Thermomix turbo 2 seconds x 3 or 4 times checking texture between each time).
Pulsing is best so that you can control the amount of chunkiness that you'll end up with (I like it a little chunky still).
Stir through the salt and pepper.
Store in the fridge for up to 1 week.
