Great question! I'm all about fast and easy recipes especially during the week. I try to stick to 30 minutes or less to prepare a recipe. If you are dealing with a meat eating family that are not fans of tempeh, tofu or seitan then I would recommend considering beans or meat analogues for protein. Gardin makes some really great vegan meat analogues that taste really good.

I also always keep about 10 cans of various beans/legumes such as kidney beans, chickpeas, black beans and canellni beans in the cupboard. These are great to toss with pasta and veggies or to whip up a quick veggie chili. One of my favorite things to make that are fun for everyone are lentil tacos- basically make them just as you would with meat but substitute a can of lentils for the ground meat (or you can use veggie ground round).

I also recommend planning a menu for the week and finding one day a week that you have time to prep dishes for the week (for me this is usually Sunday). This gives you the ability to make quick, healthy and tasty meals for the family. Prep veggies, marinate tempeh or tofu or even cook up some brown rice and store it in the fridge so you can easily put a meal together. Making fast, easy and healthy vegan/vegetarian meals doesn't have to take time and if you prep things ahead many meals can be thrown together in 10 to 15 minutes!
