I make the meals for my boxers as one is extremely allergic to beef. I make in a big stock pot, a bulk pack of pasta, 4 chicken breasts, half a cabbage and half a packet of carrots. Have also used frozen veg previously. There is one brand of biscuits which he doesn't react to, so I use them as well. Half the meal is biscuits, half is the home made stuff.
I use pasta instead of rice becaue they get the rice EVERYWHERE. I've discussed their meals with our vet and he's happy with what's in it.
I also found that some of the pet foods sold in the cold section of the supermarkets were off, even before the expiry date. So I didn't think it was worth the risk of making them sick.
Look forward to hearing more ideas.
Just remembered, sometimes I make like a tuna omlette with just egg, tuna and grated cheese.
