I've noticed that veggies are hugely important to making me feel good, probably because of the fiber and the fact that I'm eating them instead of processed crap.
It drive me crazy, though, trying to find recipes that have lots of veggies, but still a little bit of meat. I like meat, and no desire to become a vegetarian of any sort, I just want to have 90% veggies, 10% meat, or something around that. It is really hard to find that balance in recipes. I usually just take a recipe and add a ton of veggies. That works, kinda, but I really wish it was easier to find recipes that already figured that stuff out.
I got an Instant Pot for xmas, and while it isn't worth the hype, I've found some good recipes for it. One is Chicken and Dumplings. Really tasty, but I added red pepper, green pepper, celery, carrots, and onions to the recipe, and greatly reduced the dumplings. It took about 4-5 tries before I found a new version of the recipe that we liked. I'd like it if I could find that recipe straight up. "High Veggie" recipes, or something.
