Just curious to know what others do.
I do a very lazy one
Passata, garlic salt, basil, oregano, parsley knocked up while pasta cooking but it makes enough for 2 meals and I pop the leftovers in a jar in the fridge for next time and it tastes even better then.
Dd loves it (and she's fussy! She prefers it to the jar sauces or any of the recipes I've tried involving 'real' tomatoes - fresh or tinned)
But as I say I'm curious.
