I've always cooked as much as possible from scratch (this is not a debate as to what qualifies as from scratch!)
So whenever I make spag bowl, I make my own sauce. It's always tasted good and we enjoy it.
However I've been poorly and dh did the food shopping. I requested some cheats to make life more manageable right now. He bought a waitrose tomato based sauce to use instead of making our own, and I have to admit it tasted way better 
now I don't want to go back! Even though I know my version is much healthier.
How do I make my sauce taste as good! Or wibu to continue to use this sauce from the fresh/chilled aisle and never tell anyone I can't help but think I'm going to be disappointed next time i make my boring in comparison own.
When I make my own I use: garlic Italian seasoning, salt & pepper, chopped basil leaves, peppers and onions, 2 crushed garlic cloves and Passata
where am I going wrong?
