Healthy cooking and shopping tips

Recently I had made something similar to packaged Spanish rice but substituted boiled and drained orzo for the rice. There was alot more of it for the money and alot more nutrition including more fiber and less salt. For the sauce while the water is heating for the orzo, I sauteed different kinds/colors of bell peppers, onion, and garlic then added in diced tomatoes (from Aldis of course LOL) and our preferred seasonings (cumin, tumeric, crushed red pepper, etc.).
Our son though thin can consume enormous amounts of food and loves good tasting food he can consume without worrying about his LDL. When I cook, I never add salt because there is enough salt in the canned foods that I use, use minimal cannola or olive oil, and always am looking for ways to add fiber like oatmeal, pastas (preferably whole grain), brown rice, veggies, etc. We have become label readers when shopping, especially as far as fat contents and avoid all foods with any trans fats or too much saturated fats. Fiber is a huge bonus when shopping as well. Those new light Thomas English muffins make a great crust for mini pizzas.

ETA: I should mention that my own weight and cholesterol profile are much lower since shopping and cooking to keep son's LDL lower. We are even slowly getting DH to try and like these healthier foods. Since most of our ingredients are bought on sale (or at Aldis), we are finding that eating healthier can be done economically. Also we are eating out and bringing in takeout less which not only saves money but gives us more control over what we are eating. Most of my cooking is very simple and doesn't need much special ingredients.

ETA: Why cumin and turmeric?
Both taste great to us and have multiple health benefits.
Our son and I fall into the *hate* cilantro camp.
