Vegan Con Queso Dip

This is an old recipe from the 1970's that I've veganized.  It's sort of like the vegan Rotel Dip but has more vegetables and spices in it, and it's really good.  Served with Doritos, Tostitos or Frito's, it's perfect for nacho night or watching football at home.  If you don't want to use the beer in it, I suppose you could use soda water, but I haven't tried that yet.  If you really want to do it up right, you could also serve the Excellent Bean Dip from this site.

Vegan Con Queso Dip

Serves 6 to 8,  I'm guessing.

INGREDIENTS
2 Tablespoons oil
1 large onion, diced
28 oz. can crushed tomatoes, drained (any kind, even fire roasted)
4 oz. can diced green chili peppers (we like mild or medium heat)
1 clove garlic, pressed, or crushed and minced
1 teaspoon chili powder
1 teaspoon fine sea salt
1/2 teaspoon dried oregano
8 oz. bag of Daiya cheese
up to 1/2 Cup of beer

DIRECTIONS
Saute onion in oil on medium heat.
Add tomatoes, chili peppers and seasonings.
Simmer on low until blended and some of the liquid is gone.
Put in double boiler and add cheese.
Simmer, stirring occasionally, until cheese melts.
Add splashes of beer as you stir, maybe a Tablespoon or two at a time, to smooth out the mixture and keep it "open."
Serve with nacho chips or Fritos.

Notes:  You could probably substitute soda water instead of beer.  I haven't tried this yet, but I can't see why it wouldn't work.
