I am able to whip up good wholesome foods quickly because my kitchen is set up to do so. All the ingredients are easy to get to and available. It's easy to get to my bowls and pots or pans. When things are down in the storage room or in the clear, far back of the cupboard we are less likely to dig around to get to it. Human nature I guess. I know I'm a culprit of this for sure. I don't have a lot of time. I work everyday, usually 30 hours a week. I have 4 children who demand every second after school with piano, dance, basketball, scouts, homework (ahhh... the homework). Most of the time I have 20 minutes to prepare dinner. Remember, I make everything from scratch. I don't use boxes or mixes or processed foods. Things in my kitchen are organized and easy to get to. If I know I'm wanting to have beans the next day, I'll soak them overnight and then start cooking them in the morning. I have general meal ideas already set up so the ingredients are already either in the fridge or in my cupboard. It's important to have plenty of the basics; onions, garlic, and herbs (see post about herbs).
Find a system that works for you. One thing I've always tried to do is plan ahead. If I see the flour bucket low, I'll grind the wheat before I need it. If I see that my jars of nuts or grains are getting low, I'll refill them before I need it. This is primarily what I do on Sat when I'm doing my deep cleaning in the kitchen. This is really how I can be so successful with preparing good food with very little time. Here's a few pics of my kitchen. Try having open shelves. I love it. I also keep everything in jars or cans; so I don't have to worry about mice getting into them or plastic leaching. I also like how it looks.
Here's my pantry cupboard. Everything is marked and easy to find. All my baking products, nuts, seeds, grains, beans, legumes etc. go in here. I have larger buckets of them in my storage room but have these in my pantry for easy access
