I do the same, and it saves me a lot of time and (I think) money. My Vitamix and food processor are two things I'd have a hard time living without. The Vitamix is expensive, but I got a refurbished one with free shipping, and I use it every single day, often several times a day. The food processor was $30 on Amazon and is a workhorse.
I don't waste money or space on little kitchen gadgets like a garlic press, etc. Most chefs will tell you that you don't need those things and that you can do better with just a good set of knives, etc.
I freeze a lot of things in ice cube trays... pre-juiced lemons and limes, homemade chia jam, sauces, etc. Once they're solid, I take them out of the ice cube tray and put them in a plastic bag. Then I have the right amount at my fingertips when I need it. (My ice cube tray holds 2 tablespoons per "hole," so it's easy to know how much I have.) I also make sure to label everything because I've learned the hard way that even if I'm sure I'll remember what something is, about 20% of the time I don't. I get fruits and veggies when they're in season and on sale, and I freeze them. Nothing like having cheap raspberries in December!
I am mostly vegan (I do eat honey, and I occasionally eat cheese or products made with milk or eggs when I'm out, but not at home), so most of you probably won't be very interested in my recipes. :-) Two of my go-to websites, though, are ohsheglows.com and mynewroots.com. Great recipes there for those who don't require meat in every meal or those who are willing to experiment with non-meat options.
Thanks for starting this thread! Looking forward to other ideas!
