So you will have to combine it with non-pureed tomatoes and use it as a secondary ingredient.

The link below from NCHFP might work if you still have non-pureed tomatoes and you use the puree instead of the tomato paste called for.

Annies Salsa would work if you use non-pureed tomatoes and use some of your puree for the tomato sauce and paste called for in the recipes (convert oz to cups).

Tomato Taco Sauce
• 8 quarts peeled, cored, finely chopped paste tomatoes
•2 cloves garlic, crushed
•5 cups chopped onions
•4 jalapeño peppers, seeded, chopped
•4 long green chiles, seeded, chopped
•2½ cups vinegar (5 percent)
•2 tablespoons salt
•1½ tablespoons black pepper
•1 tablespoon sugar
•2 tablespoons oregano leaves (optional)
•1 teaspoon ground cumin (optional)
Note: This recipe works best with paste tomatoes, as slicing tomatoes will yield a thin watery salsa. If you only have slicing tomatoes available, use theTomato/Tomato Paste Salsa recipe.
Caution: Wear plastic or rubber gloves while handling and cutting hot peppers. If you do not wear gloves, wash hands thoroughly with soap and water before touching your face or eyes.
Procedure:
Wash and rinse canning jars; keep hot until ready to
use. Prepare lids according to manufacturer’s directions.
Preparing Peppers:
The jalapeño peppers do not need to be peeled. The skin of long green chile s may be tough. If you choose to peel chiles, use one of the two methods on page 5.
Hot Pack:
Combine all ingredients in a large saucepot and heat,
stirring frequently, until mixture boils. Reduce heat and simmer, stirring frequently until thick (about 1 hour). Ladle hot into clean, hot jars, leaving ½-inch headspace.

Remove air bubbles and adjust headspace if needed. Wipe rims of jars with a dampened, clean paper towel; apply two-piece metal canning lids. Process in a boiling water canner according to the recommendations below.

(Hot pack and process 15 min. from 0-1,000 ft. altitude. Add five minutes for every 6K feet after that.)

Below is link to the recipes, there are a whole LOT of them and you might find something you like and meets your needs. You can cook and mush up your salsa to make it less chunky.

Also instructions for peeling and de-seeding your peppers, which will make a smoother salsa.

Preparing Peppers:
Wash and dry chiles; slit each pepper along the side to allow steam to escape. Peel using one of these two methods
to blister skins:

Oven or broiler method to blister skins
Place chiles in a hot oven (400°F) or broiler for 6 to 8 minutes until skins blister.

Range-top method to blister skins
Cover hot burner (either gas or electric) with heavy wire mesh. Place peppers on burner for several minutes until skins blister.

To peel, after blistering skins, place peppers in a pan and cover with a damp cloth. (This will make peeling the peppers easier.) Cool several minutes; slip off skins. Discard seeds and chop.

Which means 35 minutes for pints instead of 15 minutes, and that's just a guess, if you are folllowing an approved recipe for salsa there should be enough acid in there even if using more than the 1Cof low-acid veggies per 7.33lbs (or more) of tomatoes.

If your salsa is thicker than a juice, cooked down like a tomato/spaghetti sauce, then I'd follow the instructions for Spaghetti Sauce without Meat, which means PCing, not BWBing, even with the added acid.

Even "Mexican Tomato Sauce" is not pureed, so I can't find any closer recipes - maybe "Easy Hot Sauce" which is only done in half pints, or Ball's Chili Sauce, which is 20 minutes for pints (it's not pureed but is not as chunky as a salsa).

That's the problem. None of the approved salsa recipes call for everything being pureed. Salsa is by its nature is "chunky" and the chunks are surrounded by the acidic liquid. Any puree used in making salsa is normally only a secondary ingredient.

So you are making a sauce. One that happens to taste like salsa. That's fine for tomatoes but pureed low-acid vegetables like onions and peppers have different safety guidelines and require longer processing times, careful acidification and are normally pureed only after opening the jars.

So if you are using your own recipe to make it we'd need to see the recipe. Otherwise it is a done-at-your-own-risk thing.
