Heat oil in a large frying pan over medium heat. Add onion and bacon. Cook, stirring, for 5 minutes or until bacon is browned and onion has softened. Remove from heat.

Reserve 1 teaspoon of the chives for garnish. Add remaining chives and bread flavouring to bacon mixture. In small microwave-proof bowl or jug combine cream cheese, cream, sour cream and grated cheese. Add onion mixture and mix until combined. Season with salt and pepper.

Heat in microwave for 1 minute intervals on high until cheese is melted together. Serve warm with the cheese twists or selection of fresh vegetables.
