You don't have to eat like a contest prep bodybuilder to drop 10 lbs. really any food that fits an intelligent macro breakdown works. I have almost a hundred various recipes built up over the past couple years that are all very tasty and pretty much all based around normal everyday staples like meats, fruits, veggies, rice, potatoes, canned items etc.
It's as basic or complicated as you want to make it. I lived off chicken, rice, hot sauce and broccoli for literally years cause it was simple, tasty, cheap, and I could make large amounts at once. Currently I make a different few recipes each week that are much more involved and just work out the macros with them. Much more time consuming, but more tasty.
