Really Fast But Healthy Meal Ideas

I hate cooking & never have time.
I have to eat a lot of food because I'm really active and have a super fast metabolism. I need lots of carbohydrates or else I get hungry within 10 minutes after eating. I need really filling foods.

I'm experimenting with fast but healthy meals and snacks and would love more ideas!

Sometimes I just eat ingrediants. Sometimes I literally just eat a peice of fruit, a handful of nuts or I literally just mix up ingrediants that I have in the fridge or laying around on the counter and eat them together and end up inventing some really good tasting things. For example, yesterday I cut up an avocado and put it in a bowl with a scoop of plain greek yogurt, a handful of sunflower seeds, some lettuce, pre-sliced cheese, then I just grabbed two slices of bread, put some mustard on it and assembled all of this onto the bread as I ate. The fastest lunch in the world and it tasted amazing.

I like quick smoothies, I just pop in a bunch of fruits, veggies, nuts, milk, yogurt, ice and frozen berries and I get a fast meal that is well balanced with fats, protiens, and simple carbs, but it still lacks in real long lasting carbs.

I also like my crock pot, because I can just place anything in it and have it ready for dinner. For dinner, I've cooked up a bunch of bone marrow, chicken livers, a big chunk of ham with carrots.

I like to roast a bunch of root vegetables at one time and then have them for a few days whenever I want something yummy to eat. These are supposed to be complex carbohydrates but they really leave me hungry after 10 minutes, even if I eat 2 plates.

I literally do eat my meat raw sometimes because I just hate cooking. But meat doesn't fill me up very well either.

I need some ideas for foods that are really filling and that will keep me full for a long time, that are fast to cook. Problem is I can't have wheat or gluten or rice.
