For many Christians Lent involves fasting and prayer.
The modern understanding of fasting is not so much "mortification" but to reinforce our prayer life.
We are encouraged to pray every time we have a hunger pain or have a passing thought of food. It is an extension of "I am the bread of Life".
If you are not the praying type but want to play with the idea write down five things you are thankful for. Refer to your list every time you have a hunger pain. Raised in a home with books? You have more than two days of food in your house? Your vehicle starts EVERY time? You sleep every night with somebody you love? You have three real friends? The list can be endless.
Neurons that fire together wire together. The association of hunger pang/prayer does not arbitrarily end at Easter. It follows us the rest of the year.
Another consideration is that meat is prohibited on certain days by certain Christian denominations. I happen to be a card-carrying member of one of these denominations.
For most of recorded human history only the very rich could afford meat so this only impacted the rich.
The rules still apply.
My parents love salmon. To them, it is eating very high on the hog. I prepare meals for them on Friday. I often buy salmon for my parents on my day to cook for them.
Last Friday we had about a half pound left after packing their food.
It went into monkey brains. Mixed with rice, cream-of-celery soup, two eggs, half a chopped onion and a bit of dill seed. Baked in the oven for an hour-and-fifteen minutes at 300F. They turned out well.
