Vegan Sloppy Joes

I've had a package of Textured Vegetable Protein(TVP), a soy flour product, since pretty much the beginning of summer but hadn't made a single thing with it. The only recipe I had really found was a Shepard's Pie adaptation and I was honestly just too lazy to make it. Then I found a recipe for a vegan sloppy joe a few weeks back and since my parents ate meat-people sloppy joes, I was feeling left out and wanted something akin to it. Hence, this fairly easy recipe and delicious adaptation:

Vegan Sloppy Joes

1 small onion, diced
3/4 cup boiling water
3/4 cup TVP
1 1/4 cups tomato sauce
1 Tbsp. mustard (I made an adaption to this by mixing ground mustard and rice vinegar to around 1/2-3/4 tbsp, as it will be much stronger)
1 tsp chili powder
1/2 tsp sugar
1/2 tbsp celery seed
1 tbsp paprika
1/2 tsp soy sauce
1/4 tsp pepper
1/4 tsp sea salt

Saute the diced onion in a pot with a bit of oil. Once it is soft and becoming translucent, add in all other ingredients, mix well, and cook for around twenty minutes on medium-low heat. Stir occasionally. Serve on either toast or old dry bread, softer bread won't hold up to this at all.
