Note: everything short of baking can be done ahead of time in the morning so you just have to chuck the pan in when the turkey comes out. These directions supersede the stuffing package directions.
Put stuffing into one or two large mixing bowls. Leave plenty of headroom for mixing without spillage.
Do the following three things concurrently:
When the above is done, add veggies, sausage, and almonds to the stuffing bowl(s). Add the butter/broth mixture a bit at a time, mixing thoroughly, so that stuffing absorbs the fluid fully. Don't add so much that it gets soggy. Season with poultry seasoning, sage, salt and pepper.
Pour into a greased casserole dish and bake uncovered at 350 degrees for 35 minutes. This can be done the moment the turkey comes out to time things right.
