batch cooking beans? (cook 5 or so cups - soak overnight, cook for 4 hours, when cool, put a bunch into freezer bags so you have quick beans when you are hungry - lots of bean recipes - like soups or even with tortillas.)
Find a source for raw, grassfed milk and then just drink it! So many vitamins!
Take an hour on Sat morning (or whenever you might have one) and make a couple of double batches of a yummy looking salad dressing. If you have a food processor, you can grate cheese and make salad dressings without really washing it in between - then you can quickly put together salads throughout the week.
For breakfast, I just ate a sprouted tortilla, some raw cheese (I ordered cheap through a coop) and some fermented bean paste - out of NT - gosh, it is easy to make, an onion, some beans - In a food processor and then ferment for a couple of days. I imagine that was faster than frozen pizza. Once fermented, the bean paste keeps for months in the fridge - also, it sounds gross but the fermented bean paste is one of my all time favorite things from nt. (I've been doing this for about 2 years now and, I must admit, my tastes are evolving a little)
Cans of sardines are pretty cheap and healthy (but again, if you don't like them... me and the baby usually split a can of sardines and we just eat them right up)
If you can find kefir grains, that is easy - just put it on the counter every day... and then make smoothies.
I make bone broths every couple of days - but it took me a year and a half to figure out that wasn't hard. (so full of vitamins and minerals though - I wish wish wish I had fed my kids this when they were babies!!! To get them used to the taste - so healthy!!!)
If you ate better, I bet you would feel better so you would have more energy. Like, I am kind of bad at eating breakfast - often my husband helps out there - and when I eat a solid breakfast, I have energy for the day. It really helps. We usually eat miso soup made from bone broth with a little dried seaweed flakes, scrambled eggs and a little kim chi. (kim chi, I make a gallon every two weeks - it is a pain to find that hour to make it but nice to just have in the fridge - we don't end up eating much vegetables otherwise)
Good luck, It is hard to think of easy ways in - I am so in the thick of it and things that used to seem hard are getting easy. It is a pattern, a rythm, and so many blasted dishes!!
