These sausages will certainly do in a pinch...when you do not have gluten free sausages on hand.   Although these were not your typical sausage in a casing, these were pretty good -  not as excellent as the place where I buy them, but darn close.
Note:  these were even better the next day.  Next time, I would make them up the day before, then refrigerate until ready to cook.
Seasonings:
1/2  Tblsp. Garlic powder
1 tsp. Fennel, Salt, Whole Savory
2 tsp. Sage
½ tsp. Basil, Oregano, Paprika
¼ tsp. Lemon pepper
pinch of allspice
Mix well, and store in an airtight glass jar.
1 Lb. Ground Turkey (beef would also work nicely here)
1 Lb. Ground Pork
2 ½ Tblsp. Of Seasoning Mix
Mix the meat and seasonings in a bowl,and scoop up some meat about the size of a meatball, then I rolled it between my hands to create a sausage shape.  This amount gave 21 sausages.  I placed them on a baking sheet and covered with plastic wrap to refrigerate for 1 hour.
Heat up a frying pan on medium heat, with a drizzle of olive oil, and place the sausages in the pan to brown.  Turn the sausages, browning all sides - in total this took about 15-17 minutes.  These sausages can be made this way, or into a pattie shape, or just cooked up crumbled for any kind of sausage dish.  It would make a great cooked crumbled filling in a quiche or a frittata, or in a pasta dish too...so many possibilities...yum!
