We try to eat as healthy as possible. 2 adults, 1 toddler.
I cannot offer much in the breakfast dept. I generally eat a hard boiled egg and some veggie strips, plus coffee, in the car. Anyone want to pimp THAT?
Dinner, things we do:
grill meat on sticks. I cut chicken thighs (cheaper + more flavor) in two and thread on skewers. Grill, brush with soy/hoisin/bbq/whatever, serve with rice and veg (can grill veg too, makes it fast, easy).
Put new spices or sauces on stuff you already make. Ie try chili powder, chinese 5-spice, jerk seasoning, etc. Easy, fast, and can spice up leftovers too.
steak... make steak salad, or little bits into steak quesadillas, or steak fajitas. Less meat per person, still satisfying, adds variety.
hamburgers - try salmon burgers, lamb burgers, turkey burgers. Different kinds of toppings, too - for lamb try tahini or hummus, different kinds of cheeses, etc.
grill sausages instead of hot dogs (grill a few extra and put them in pasta the next night, along with a bag of baby spinach. Wilt the spinach and toss with EVOO).
Try different fish - we like chunks of tuna or swordfish on kebabs with veg (red onion, cherry tomatoes, bell peppers, zucchini, and pineapple are favorites).
What I tend to do is make a big "traditional" something (roast chicken, grilled steak, etc) one night and then disguise the leftovers later in the week - chicken soup with coconut milk and curry, steak fajitas, etc. I try to totally change up the flavors so it's not like a "theme" week or anything! Yummy, healthy, and easy-peasy especially the second night! DH refuses to just eat "leftovers" but will accept them in new clothing, so to speak, so when he says, Gee that was yummy (to leftovers) I consider myself victorious. Also a very handy strategy for when it's just too darn hot to cook. Grill outside 2-3x week and you're set.
