you can add the banannas to your favorite pancake recipe. Also adding some to a cookie or cake recipe can add a new flavor and it makes them more moist too!!! Sometimes I mash a bananna with vanilla if I don't want a strong bananna flavor...a tsp or so per bananna or to taste.
As to the tomato sauce, you can take a can of crushed, whole,cut tomatoes and run them through a food processor and make your own sauce. Start by adding a tiny bit of herbs and let it simmer for about 30-60 minutes and then taste. Keep track of the herbs and garlic as you add it. I like to add the premixed dried Italian herbs (in a bottle) to mine, and also garlic, onion or onion powder. I do add a bit more oregano.
To me the canned/bottled sauces are too sweet and I don't add sugar to mine. Also adding in a bit of tomato paste at a time can change up the flavor.
Sorry I don't have any actual recipes for the sauce, I am a fly by the seat of my pants sauce maker ususally :D:D:D
