My kitchen is practically my laboratory, too, and I have tried many things throughout the months of having lived on my own.
The first thing I tried from scratch and random ingredients is a 'salad bowl' with rice, lentils and cheese, and it's pretty yummy, and sometimes, I add a little leftover teriyaki sauce so it'll taste just a bit better, too. I occasionally replace those lentils with chickpeas, and then it's also good.
I have also tried making cauliflower soup from scratch by also adding a little sour cream, which turned out good but is probably better when spicy, as well as lentil-carrot soup (since someone else gave me a big bag of carrots back then and didn't know what to do with most of those other carrots otherwise), which is also pretty good, and since I'm 1/32 Indonesian, I also couldn't resist to try lentil soup with a little peanut butter for an oriental twist one time, which also tasted pretty good.
Indeed, since a tonsillectomy is just around the corner for me, I even have some potato/pumpkin/purple carrot soup and broccoli/cauliflower/carrot soup in the freezer (which I made about a month ago) to thaw out and (try to) eat later on, of which I already took a taste, and they're good to go, too, as well as full of vitamins, which I will eventually need, too.
One of the more recent successfull experiments I did in my laboratory kitchen is the good way of making 'croutons' out of chickpeas. I use dried chickpeas (canned ones contain more salt, and I'm trying to not eat too much salt), so I let them soak at first, then after letting them soak, I boil them until they're good enough to be stir-fried in a good layer of olive oil, and subsequently spice them with paprika, curry powder, salt and pepper, which makes them taste amazing. The 'croutons' are best to be eaten with pasta, with or instead of potatoes, and a piece of (fake) meat, but if oven-baked rather than stir-fried, they're amazing with soup. :9
