Re: 30 minutes or less recipes???
If you are on FB, "LIKE" Cooking Light (magazine). Every day they post a link to a recipe called "Dinner Tonight." As a general rule, they use ingredients you would normally have on hand, can be made in <30 minutes, are healthy, and taste good!
I probably find one new recipe this way every week. I tend to plan a weekly menu/grocery list, so I print out recipes that appeal to me and add them to the following week's menu/grocery list, rather than actually cooking them the day they are posted.
