Applesauce Tomato Sauce

Suggestions would be appreciated!

Ingredients:
olive oil
1 small onion, chopped in half then into thin slices
1 x 28 oz can whole plum tomatoes, drained of most of its juice (I used Nicola San Marzano plum tomatoes, which smelled amazing)
1/2 clove garlic, chopped
1 1/2 tsp allspice
2 tsp basil
1/2 cup applesauce (I used a single-serving plastic cup)
1 small apple, mashed with a potato masher

1 lb linguini

In a large nonstick skillet, heat about 3 Tbsp olive oil until it’s hot. Toss in the onion and move it around so it’s coated with olive oil. Cover and leave until the onions turn brown/black and kind of stick to the bottom of the pan. Add the tomatoes and roughly crush them with a hard rubber spatula. Add the allspice, basil, applesauce, and mashed apple. Cover and put on medium-low heat for about 30 minutes.
Meanwhile, bring a large pot of salted water to a boil. Drop in the linguini and cook according to package directions. Drain.
Enjoy!

Note: the sauce might be kind of soupy, so I suggest using a slotted spoon to serve it.
