Frozen and canned fruits and vegetables are always cheap and plentiful. Fresh is always going to be more expensive because of the way growing seasons work.
In the future we will need more localized greenhouse farming because of water issues in the Southwest where most vegetables are grown (for u.s. consumption)
I mean... how many calories are in that big thing of salad mix? A few hundred probably. Compared to 1500 calories in a pound of ground beef.
Most fruits/veggies are pretty bad at giving calories. Even the mighty potato is only 400ish calories for a pound .
Grain/beans trounce meat in terms of energy per dollar spent, but I think that's why it's become so common to do grain/beans + meat. Meat is way more calorie/cost efficient than veggies, so it's the perfect way to modify your grains/beans to be tastier and more filling.
So yeah, pushing that money to make it so that veggies are cheaper per calorie than meat would be super nice. So super agree on in door farming, I hope we get more of that.
