I have talked about doing similar, and had a few aborted attempts over the last few years, but have recently enforced 'Meat free Monday' in our household.
Wifey gets anxious and uptight about it - even tho I opt to do the cooking on that night (yes and others too

). Funny thing is she was a "fish don't have any feelings" vego when we met. Er..

MFMonday is working well and wifey actually said to a friend at dinner the other night (as she passed over the roast beef

) that she "felt better and 'lighter' because of the one vego day a week". Imagine if it were 2 days a week (my next aim). "Steady there cowboy - let's not get crazy."
BTW - lunch is fair game and it is only the evening meal that is a no meat zone. When you stand back, it kinda seems ridiculous that it takes effort to think and act so that only one main meal a week is meat free.
Says a lot I reckon.I have always believed that eating a small (and I mean 1-2 small serves a week) amount of red meat and more fish (when affordable) with a
vegetable based diet is the winning combo. I try to eat vego (he he - or swimming vego) during the day to balance a bit.
Unfortunately everything in our society is
geared towards each meal being focused almost exclusively on what kind of meat we consume and the way it is prepared. The healthiest most neglected aspect (vegies, salad etc) are hastily shoved onto 30% of the plate for a bit of colour.
Meat is a bit like a drug, most folks feel short changed and like they missed a 'hit' when they actually have a meal without meat. Kinda like junk food addicts and Maccas etc.
Wrong philosophy I reckon and
if as much effort was made with veggies - they might actually be desired as a main course. Which as the food pyramid shows is the ratio they should actually be.
I'm, not gonna judge carnies, vegos, vegans or any other combo - it's your body, so your choice.
What does surprise me is the resistance and indeed borderline hatred heavy meat eaters (that would be about 80% of the country) have for those that choose not to eat meat. It's like trying to actually
take a bone away from a bull terrier. [}:)]Grrrr Grrr..

Territorial lot those carnivores.

BTW - the trick for meat eaters (like myself) to feeling 'full' on vego is to cook something a little stodgy at first. Gives you that 'My guts will be busy with that for a few days' feeling that we love. Last night it was risotto with fetta, fried pumpkin, peas n parmesan. Normally I have proscuito or bacon in there but what's not to love about risotto ect?
Give a night a week vego a shot - you might just like it.
