Assuming you want a bit of a mix of fast, cheap, easy, and healthy(ish), my go-to's are definitely:
- Breakfast: Omelet (it's a lot easier and quicker than you might think). Throw in some leafy greens and healthier cheese (provolone or mozz instead of american)
- Lunch: Fried rice. Fry in olive/coconut oil, those contain healthy fats. Throw in a simple frozen veggie mix, and some chicken/turkey. Season the shit outta it with chili powder, ground mustard, pepper, garlic powder, onion powder, and soy sauce.
- Dinner: Pan seared chicken. After you make your breakfast, throw a chicken breast (or two) in a ziplock with olive oil, paprika (smoked paprika is even better), pepper, cayenne powder if you want spice. Shake the bag around a bit and let it sit in the fridge until dinner time. Then just pan sear that bitch in a covered pan on low (helps retain moisture).
