Fresh veggies are alway the best, but frozen is the next best and much easier. Most frozen veggies all you need to do is put in a microwave safe dish, with a tiny bit of water and pop in the microwave.
For dinner tonight... just put it in the oven,
pork loin, sprinkle with garlic powder and pepper, place in the center of a glass baking dish. Cut up potatoes (I leave the skins on, making sure I scrub them first) and carrot and place them around the roast. Add about a 1/2 cup of water to the pan, put in the oven at 325 for about an hour.
Grilled boneless chicken breast can be your best friend. Marinate the chicken breast in a bowl or a big ziplock for a few hours, overnight is better). Italian salad dressing makes a great marinate or there are tons of varieties in the store. (note: you don't even need to marinate, but I think it keeps the meat moist). Another trick to helping keep it moist is cut the breast in half, it cooks more evenly so the ends aren't overcooked. Now you can have the chicken breast just as is for dinner. You can cut it into chunks and toss on top of a salad for a light meal. You can slice it up to make sandwiches. You can use the chunks to make chicken salad.
For a side dish, a favorite for the kids, ranch potatoes (hot or cold). Peal and cut potatoes into chucks, boil until cooked, and drain. Mix dry ranch dip seasoning with sour cream and mix over the pototoes. If you'd like add some chives, scallions, or chopped celery.
Tacos are simple. Brown a lb of ground beef, drain off excess fat, add a taco seasoning packet and water (the amount is on the back of the package), simmer. You could also saute some onions with the ground beef. Serve on taco shells or tortillas, topped with any combination of the following sour cream, salsa, shreaded lettuce, shreaded cheese, chopped tomatoes, chopped black olives. You could also drain and rinse canned corn or black beans and add these.
Have fun!
