Well I have a far better replacement for lean or fat hot dogs which is cheaper $2 a pound, extremely lean with almost no fat and does not brake up at all, Chicken Gizzard. By placing a couple in the microwave for 30 seconds it will kill reproductive bacteria if any yet leave raw. The microwave also shrinks the tendon on the muscle into a ball making the tendon very easy to trim off the muscle. Let cool for a few minutes and drop in. My Oscars love them and no gill particles. I freeze the bulk in 5 portion sandwich bags inside a larger quart freezer bag. The freezing preserves the huge $2 pack of gizzards and also tenderizes the muscle by crystallizing the tissue. Chicken gizzards are super lean and have very little fat and no trans-fat, no cholesterol, but are high in protein and really give my Oscars something to chew on.:clap:
