I’ve gotten in the habit of meal prepping on the weekends, mostly various vegetables of different sorts—lots and lots which makes up most of my lunch and dinner meal volume during the week. I’ll pair four or five different vegetables with some kind of protein source each meal, such as roast beef, BBQ chicken, pork chops, etc.
The veg doesn’t have to be bland. I like doing roasted cauliflower in garlic and butter, sweet potato bites, zucchini squash in butter topped with Parmesan cheese and broiled, and many others.
When I do this regularly, I’m able to achieve/maintain an ideal weight while staying full for hours after each meal.
