Heh.......my two will eat the toaster if I mix some canned Salmon or Mackeral with it
I see no reason to buy her canned or rolls of Dog food TM. Save your money and search your cupboards.
Save the broths from dinners you cook for yourself........Ie..roasts, chicken or turkeys........any meats like that. I have done this even before I started cooking for the dogs. I just freeze the broth in little freezer bags, and whip it out to pour over dog food when necessary. Lots of flavor.
Nothing wrong with frying up an egg if she likes them (my two don't care for raw eggs) and toss it in her canadae.
You have already mentioned cooking up some ground chicken, turkey, or whatever with veggies.............great plan.......but.............
When you have a meal at home, chicken, bison, whatever..........bag up the leftovers in individual baggies, just the right amount to toss in.
Another thing I used to do with bored doggie pallets...........get some peanut butter, just a tablespoon......mix with some water to make a sauce, instant gravy that mine LOVE!
Don't make it too hard on yourself...........use what you have since she is getting what she NEEDS from her canadae, you can give a tidbit of something she enjoys mixed in
