In a large saucepan on medium high heat, melt the butter and add the oil from the jar of tomatoes
Fry the onions until translucent
Add the garlic, sun dried tomatoes, tomato puree, sugar, paprika, and oregano
Cook for a few minutes, then slowly add the stock and lemon juice
Bring to a boil, then simmer for 10 minutes
Take the pan off the heat and use a stick blender to give the sauce a quick blitz, leaving some chunky bits
Put the pan back on heat, add the spinach and double cream, and heat through
Stir through your cooked paccheri pasta
Garnish with cherry tomato halves
