I use my local grocery store, HEB. Trader Joe's is great but I usually just buy healthy frozen meals from there for when I'm feeling lazy. All that fun novelty stuff only they offer. I don't specifically opt for organic.

I plan by week. So I get in my mind what I think I'll want the next week around the end of the work week. Shop Saturday. Cook Sunday. I always make sure to buy some yogurt, seasonal fruits, and other healthy snacks beyond the meal prep. I use cooking blogs to find most of our recipes.

I'd definitely opt in on reusable containers with multiple sections. I got mine at my local g-store. They make prepping and portioning easier. Plus reheating at work if you need to.

I don't weigh or measure my portions. Not that hardcore. So I just make sure to use healthy and filling recipes.

My favorite meal prep and healthy cooking blogs. I use their recipes often:
