Something with Gravy on Toast

Whenever my parents went out for an evening, my mom most often made one of these two dishes -- chipped-beef on toast or tunafish on toast.  Exploring ideas for recreating these dishes, I modified hers and the Joy of Cooking "Chipped Beef and Gravy" recipes to create this one.

8 oz cooked red rice (Gao Do, black rice would probably be good, as well)
some (not too much, but just enough) vegan sausage, cooked and chopped-up
3 Tbs oil
3 Tbs minced onion
3 Tbs minced celery
3 Tbs all-purpose flour
2 cups almond milk
salt to taste
slices of toast

Heat in a medium saucepan over medium heat:
3 Tbs oil

Add and cook until the onions are golden:
3 Tbs minced onion
3 Tbs minced celery

Sprinkle with:
3 Tbs all-purpose four

Remove from the heat.  Add slowly, whisking constantly until well blended:
2 cups almond milk

Add the rice and sausage and return to the heat.  Simmer until the sauce thickens enouch to coat a spoon heavily, about 10 minutes.
Salt to taste

Serve on:
Toast slices
