Here are a few meals I cook ever week. Breakfast I use instant oatmeal w egg whites and a banana add some cinnamon and a little honey. Lunch chicken breast w instant brown rice & brocoli. Also ground lean turkey w baby spinach & multi grain pasta. Tuna w some muatard and bit of relish( not the greatest but quick and good no carb meal in the evening) with ezekiel bread if I want carbs. Dinner I have tilapia w greens, I dont precook this, fish has to be fresh. Most of these I fix all on sunday, enough for about 7 days. Put em in tubaware and good to go. And it all takes under two hours. I do change it up weekly so as not to get burned out. Take that and a gallon of water to work and good to go, I also will have aminos like modern bcaa or recoup in between meals, or occasional protein shake. Just some quick ideas bro. Pre cooking and portioning all makes me have no excuse to stay on diet 100%.
