Soup anon is great but let's be honest, he's polish. He's still cooking in a pot on a stove and has to give a small fuck about his ingredients and their preparation. He browns flour base for his chowders, etc. You have to clean the pot AND the stove (as soup anon's famously disgusting stove shows).
Not shitting on soup anon, just saying it can be even easier than this.
There is another way.
Step 1: buy slow cooker (< $30 for 7 quart (big) online/at walmart etc) and meat thermometer ($13).
Step 2: buy any meat + salt + pepper + garlic powder
Step 3: put spiced meat in slow cooker and turn the knob to "low"
Step 4: when the meat thermometer reaches temp (165 chicken, or 145 for pork/beef roasts), you are done.
You now have 7+ lbs of meat for the rest of the week. Freeze it, refrigerate it, add it to anything you like, or just eat it.
I have 7 lbs of chicken thighs that i paid $1.09/lb for going right now. That's several pounds of meat for less than a mcdonalds run. It's going to last me an entire week (I eat a lot of meat cuz I lift).
There. That's the secret to food. Cleaning is literally just washing the thing out afterwards, takes 30 seconds.
Bonus: want veggies? Put veggies or potatoes in at step 3.
