I have just done the following:
soften some onion and garlic in a pan with oil
throw in some other veggies - peppers, courgettes, corn, aubergine, tomatoes, mushrooms, etc. and soften
add some herbs - I used basil and also some black pepper
Empty bottle of passatta into veg
warm through until all cooked
Add a tub of creme fraiche and stir; warm through
Today I have whizzed it all up with the hand blender; normally leave it whole.
I have served with meat balls, pasta, grated cheese and garlic bread for the girls (DD and Katz's DD1) and will give DH and Katz's DH the same later. I'll have it without meatballs.
