Gravy! Yay for gravy! It goes great on everything, including
mashed potatoes. 
It's also great to pour in a baking dish full of chopped veges and then bake it until it's a casserole.
Talk about easy.
I make it with olive oil so there is NO cholesterol, no trans-fat, nothing yucky like that, just delicious, flavorful flavor.
Basic white gravy is easy to make. Oil heated in an iron skillet, sprinkle white flour over it, stir it in until you have a thick paste and add liquid, stirring constantly and adding more or less liquid for desired consistency. For liquid I use water or vege broth.
If you want brown gravy, brown your flour by putting it in a skillet with medium heat until it is dark enough for your brown gravy, then make gravy like you normally would, using the browned flour.
Once you get it to the consistency you like, add your seasonings to taste. I like salt, pepper, garlic and cumin in my basic gravy.
To make vegan sausage gravy that people will want to drink from the pan, cut up
Seitan Sausage, plenty of it, you want a really sausage-y gravy. Use less salt in your basic gravy because the sausage is salty, too.
Put the sausage in a skillet with a little oil and brown them up. Add the seitan to the basic gravy at the
very last minute before serving so the sausage doesn't absorb the liquid and become soggy.
