I discovered these meat recipes recently, OP. They're for weight loss (because they all use 99% fat free ground turkey) but you could absolutely use higher fat ground turkey, or even ground beef, and use the seasonings to make chorizo or breakfast sausage. (If you use higher fat meat, you can eliminate the baking soda dissolved in water and the cocoa powder that some of the recipes call for).
I started making my own "chorizo" with this recipe and I put it into breakfast burritos with egg, black beans, cheese, sometimes avocado.

Also I think there is "less-processed" bacon you could buy too right - nitrate-free bacon?
finally, we get a lot of sausage and bacon from our spring/summer CSA (community sources agriculture?) share. I have to think those meats are less processed than what you buy at the supermarket. Maybe see if you can join one of those or buy breakfast meat from farmers markets.
