We buy it because it's cheap. Our favorite preparation: cover fillets with Rotel (Mexican with lime & cilantro variety), bake for about 20 minutes at 375 F. One can well drained will cover two nice sized fillets. Put fillets on a foil covered sheet pan, sprayed with a little Pam, before covering with Rotel.
We're trying to commit to about 2 fish meals a week. For a second meal, we might simply cover fillets with olive oil, lemon pepper, sometimes Mrs. Dash. Same sheet pan in the oven at 375, maybe only 15 minutes without the Rotel. It's not bad either way.
