I began making my own sausages for two reasons - One, I didn't want nitrates, dextrose, lactose, or milk protein isolate in my sausage. Two, I hunt, and have a surplus of meat that is usually too lean to eat on it's own... nothing a 60/40 ratio of wild hog to raw grassfed beef suet won't fix when spiced appropriately and shoved down a casing.

That being said, a favorite recipe of mine with polish (and Italian) style sausages is to chop them with chopped spring veggies (zucchini/squash) and stuff the mixture into bell peppers. A little hard cheese on top if you eat it. Bake these (I use muffin tins to keep the peppers from falling over) and serve.

If you were to cube sweet potatoes with this mixture, and use the very small "sweet" bell peppers that are very much en vogue currently, I'm sure it would be a hit with the kid - sweet, spicy, crunchy, savory... I just ate a steak and yet I'm now craving this...

Can't help with the kielbasa, but my 3 year old loves regular sausage links. I get them locally, uncured and unsmoked. I cut them in half lengthwise, peel away the casing, and cook on the griddle. He loves them with mustard and calls it "steak". He also loves his bacon with mustard.

My mother-in-law is from Austria and in her area they would take sauerkraut, rinse it out in a strainer, then shake the excess water and simmer it with garlic and onion, add a little tomato sauce, and then add the pre-grilled or fried kielbasa.. I thought it sounded disgusting until I tried it!

As an oddly but VERY particular eater as a child, I have some ideas you could try that may surprise you. As a general guideline, i pretty much ate like a raw foodist and Julia Child had had a baby. I hated any kind of cooked meat, but steak tartare, any sort of cold smoked ham, any kind of salami, any kind of cold meat was totally up my alley (except for aspic). Even cured salmon and pickled herring were among my favorites. Fat was great, again, as long as it was served cold, like the cured fat on meat or butter. At night my go to meal was an almost 1/4 inch of butter on rye bread with hot black tea or the same thing only with layers of ham and havarti over the butter in the toaster oven. (No more rye bread for me, rather sadly).

Sour things were great, again, i LOVED sauerkraut but begged my Mom not to cook my portion and (probably very annoyingly) complained about cooked cabbage and mushrooms. My Mom used to make homemade chicken stock which I liked, but it was lemon soup that was my favorite, done with only fresh squeezed lemon juice and rind into the chicken stock.

Vegetables were iffy. I never much liked potatoes (and we ate them daily). I think more butter and seasoning would have helped that situation. Again, I preferred raw carrots to cooked, etc etc.

I do think generally children respond well to cold, cured, raw and cold smoked protein better than they do to cooked protein, broths are great too. You could even try a well made pate. Even most SAD kids love hot dogs. You might be surprised to see what kids will eat if exposed to it at a young age.

Nothing better than a big pile of kielbasa and scrambled eggs. Cube the kielbasa. Cook for a few minutes in a pan in lard/coconut oil/butter/ghee (pick your favorite). Then, cover with eggs (either just cracked into pan or scrambled) and cook until mixed and finished. Then, try to stop yourself from devouring the entire pan and do your best to leave some for your family. :)
