I make most of my stuff at home too. My wallet is grateful :D

Crockpot is always good for things like a nice chuck roast. Sear it before putting it in.

This isn't a recipe exactly, just more guidelines. I usually put a bit of olive oil, seasoning of choice (sometimes steak seasoning, other times being lazy and using a slow cooker spice packet), onions, celery, potatoes. Few hours later, depending on the size of your roast, you have an easy, tasty dinner.

As for fast in general, seafood generally tends to be one of the faster things to cook. Quick easy way to go is to make sure you have clean shrimp on hand. I usually keep a lime cilantro salsa in the pantry/fridge, toss it in there to season them and make rice to go with. Rice in a rice cooker takes about 30 min, if you want it even faster, grab one of the instant rice options of your choice (boil in bag, microwave, frozen ones etc. If you go that route, aim for the frozen rice with veggies. Slightly healthier and you won't need to worry about another side since veggies are with the rice).

But since you like the crockpot... Do you have a pressure cooker? They're much faster than crockpots but you have the same tender tasty sort of meals. 

When I worked in an office I would often do  meal prep the same day I bought groceries- that way you can plan a week's worth of meals prep and simply warm up when your ready! You should check pinterest for LOADS of ideas on meal prep so your not eating the same thing over and over. It takes less time and money than you think it will.

1. Tuna Sandwich

5. For crockpot you can use a soup base, like cream of chicken or cream of mushroom cream of anything: https://dontwastethecrumbs.com/2015/04/how-to-make-homemade-cream-of-anything-soup/

Then add veggies/meats to taste, rices, potatoes, carrots, squashes can all do well.

6. Chili/Soup

7. Homemade Hummus (inexpensive but time consuming)
