Dinner salads can be nice. I have a love/hate relationship with salads but you can really dress them up and get creative. One of my favorites is grilled chicken with montreal steak seasoning or lemon pepper seasoning, feta, almonds, grapes, apples, cucumbers, red onions, and olives with a balsamic dressing. I also like an asian pork style salad - you can get any kind of glaze you want from teriyaki to curry to thai peanut sauce and grill or oven bake the pork cutlet then shred it over the salad. You can add some asian chow mein noodles, almonds or peanuts, chopped pineapple or mango, onions, and diced peppers. If you have peanut sauce left over you can go ahead and use that as a dressing too for the salad
I second the idea of getting a crock pot. You should also look into one pot and casserole recipes. There's one casserole I've made a few times that requires you to basically just brown some chicken and then put kalamata olives, sliced lemons, the chicken, a bunch of orzo and chicken stock in a pyrex and bake for a half hour. About 10 mins of prep and then the baking time. Easy
