Need recipe for making big tomato pasta sauce

For about 30 people any help with this?

This is a nice pasta sauce recipe, you need fresh tomatoes to roast for extra flavour and added sweetness to the sauce.
Ripe tomatoes
Salt/ ground black pepper
2 cloves garlic crushed
1 onion chopped
2 tablespoons tomato paste
Fresh chopped basil, or parsley
Drizzle of Balsamic Vinegar
1 tablespoon sugar
1 teaspoon curry powder.
Cut tomatoes in half put in a roasting dish cut side up sprinkle with salt and ground pepper, and drizzle balsamic vinegar over them.
* Bake 180c about an hour till almost cooked.
Pre fry onion and garlic till soft, place in a large saucepan with tomato paste seasonings curry powder, sugar when tomatoes are roasted remove from oven cool, scoop out centres put in the saucepan discard skins.
Simmer a little to combine ingredients and tomatoes are soft but there are still little chunky bits there.
Cool Add freshly chopped basil or parsley.
For 30 people you will have to make a bigger quantity, i'd do 2 roasting dishes of tomatoes and double everything else, taste as you go and add more garlic, curry powder, seasoning if needed.
For a easy meal cook your favourite pasta, add sauce and gently heat through, serve with a nice salad and hot crusty bread...

if you are using tomatoes the truss kind with the stalk pop that in your tomato liquid in a ziplock bag overnight, then fish out and finish and your soup/sauce the next day (or when your ready to use) will taste more "tomatoey" you can even do that with canned stuff too if you have enough stalks
best yet is when you grow your own tomatoes and there is plenty of vines to go around
