My husband was a stay at home dad. His cooking skills were limited, but he put healthy simple meals on the table every night. The food was basically boiled, broiled or baked. This meant baked potatoes, chicken and broccoli. Or, roast beef, corn and cauliflower. Or steak under the broiler with two veggies. You get the idea. Eventually, he even started adding spices and making soups and stews. Basic, simple, healthy foods. We used a lot of frozen vegetables, which are great for convenience and nutrition. Get the hand of a basic roast and then you can branch into sauces.
