I love to cook, but when I don't have time or I'm too tired I have bell & evans frozen precooked chicken which nukes in 3 minutes or so. I add some mayo, horseradish etc., cut up fresh veggies, add some cheese, often add dressing with sour cream and dessert is berries with heavy cream, stevia, nuts and cocoa nibs. It still takes time to cut the veggies etc. but it is worth it. I prewash a lot of veggies and store them in a crisper so they're ready to cut and eat for whatever meal I want them for or for a snack. When I cook I usually cook for myself and I store the food in glass containers in the fridge, usually things will keep for a few nights at least. I would learn to cook some things like this because it tastes so much better and that alone is worth it. No frozen veggies etc. for me, I want everything fresh otherwise it just tastes awful and you're definitely not getting the nutrients and benefits that way. Nutriblasts are another fast meal, with veggies, berries, flax, nuts/seeds etc. There is still some prep but again much better than processed stuff. I never add the protein powders to any shakes, haven't had them for a while because they give me the runs, whatever is in them it doesn't agree with me at all.
Most of the meals I cook from scratch can be done in 20 minutes to 40 minutes in a pan or broiling etc. I rarely bake dinner type of meals.
