1In a large, heavy-based, deep frying pan, heat oil on medium. Saute pork and onion, 6 to 8 mins, until pork is well browned and onion softens.
2Stir in tomatoes, treacle, sugar, mustard, garlic, chilli and bay leaves. Bring to simmer. Reduce heat to low and simmer, covered, for 15 mins.
3Mix beans and vinegar through. Simmer, uncovered, 4 to 5 mins, until sauce thickens. Season to taste.
4Using a large spoon, make 4 indents in mixture. Crack an egg into each indent. Cook, covered, 3 to 4 mins, until egg whites are completely set. Scatter with rocket leaves and crumble feta over. Serve with toast.
