Salads can be a very healthy, and quick meal to eat, but you need to mix up the ingredients that you put into it every few days, or you will not be getting all the nutrients you need. Plus, the fact that you are only using bleu cheese dressing on your salad is probably giving you too much fat.
You need to eat at least 3 meals per day, and possible 5 or 6 (much smaller, but nutrient dense meals) per day. Otherwise it throws your metabolism and blood sugar levels way out of whack. This can lead to serious problems down the road.
Salads are great, but please make sure that you mix up the ingredients every few days so that you are sure to get all of the vitamins and minerals that you need. Here’s some things to try: different lettuces (don’t use iceberg because it has virtually no nutritious value, but do try butter lettuce, romaine, baby greens, red and green leaf lettuces and mixes with dandelion greens, chicory, arugula etc. Trader Joe’s has lots of different bagged selections) then try tomatoes (heirloom, grape, cherry, vine ripened tomatoes) then try beets (raw or steamed and sliced) carrots, broccoli, cauliflower, apples, dried cranberries and cherries, sliced turnips and radishes, water chestnuts, bamboo shoots, beans and legumes of all kinds (garbanzo, navy, kidney, lentils, peas, pinto, black eyed peas) chopped hearts of palm, kalamata olives, sliced banana peppers, raw red and green bell peppers, mango chunks, strawberries, peanuts, walnuts, sunflower seeds, tofu (raw or baked) and small pieces of different kinds of cheeses (don’t over do it with the cheese and go very light and easy with the creamy dressings) olive oil and vinegar (try different kinds of vinegars) is your best bet and have the dressings on the side, so you can monitor how much you are really eating.
And like @zenvelo said, you need to add in some comlex carbohydrates to your meals, like whole wheat bread, pita, tortillas or grain based dishes like tabouli, wheat berries, or brown rice or wild rice or whole grain pasta.
You should also be getting some non fat or low fat dairy products like milk or yogurt, to make sure that you are getting enough calcium, without adding too much fat.
If you feel like you don’t have the time to fix food to eat during the day, then make a point of throwing some prepacked snacks into your insulated lunch cooler (or take them to work to keep in the fridge) some fruit and veggie packs (Trader Joe’s has lots of combos) low fat string cheese, nutrient dense (but lower fat) protein bars, whole grain crackers, hummus, low salt, low fat pre-bagged popcorn, canned nutrition drinks like Ensure, yogurt, nuts of all kinds and trail mix, pre-made sandwiches and wraps (from Trader Joes).
There’s a whole world of food out there. Salad is great, but it should not be your only meal. You might want to look up some recipes (or we can supply you with some) that you can make ahead of time, then freeze individual portions that you can pop into the microwave when you get home (or put in a hot thermos to take to work) like: chili, lasagna, burritos, soup, stew, spaghetti, mac and cheese, stroganoff, etc. Trader Joe’s also makes a whole bunch of great canned and cartoned soups, just pour into a bowl and heat in the microwave (add frozen or fresh veggies or whole grain pasta if you want). Make eating well, be a part of your every day life, not just an afterthought, or your body will pay the price down the line.
Let us know what you like (and don’t like) and we’ll try to supply you with some easy to prepare ahead of time recipes, and some short cuts for making other dishes easier to make.
