I love to used different seasonings on my chicken and veggies. Just make sure that they are low or no sodium. I can add seasoning to my chicken throughout the week or put it in low carb tortillas and make a taco with some lettuce or other veggies. I also love putting hot sauce on my chicken.
I also eat a lot of brown rice. I buy the kind that you can boil or microwave. It comes in a box like this. I do buy as much generic stuff as I can. My husband and I are both eating clean but our kids are not, so buying two sets of groceries adds up. You can eat healthy through on a budget and most of the time generic tastes the same. You also will be going through a lot of the same things. You will be buying stuff like this in large quantities so save money where you can.
Like I said sweets are one of my biggest weaknesses. I love them. I found that chewing gum does help and I really love this gum because it comes in all sorts of delicious flavors. I know they sound weird but they are really good and at least give you time to rethink that bad decision you were about to make.
Good luck and happy meal prepping!
