Lunch does not need to be complicated to work. A protein, a vegetable, and something filling on a plate, and you are done.
When meals get complicated, people skip them or grab junk. Simple meals are the ones you actually eat every day.
Pick three or four lunches you like and rotate them. Chicken and rice. Eggs and fruit. Tuna and greens. Keep it that easy.
Fuel your afternoon the simple way, then get your training in.
Now go watch today's cardio video. It's up. Get it done.
