Everyone can grow flowers and vegetables indoors if there is light and warmth and a bit of inclination. Why do you need to grow your own if you can purchase what you need at the local market? You don't need to, but you may want to just the same to appreciate the wonderful world around you and to have easy pickings for those times when you are just too tired to run and get the scallions you need for that recipe...
To grow your own scallions, you just need to save the root end of a scallion and place it on a soaked napkin by a window sill, roots down. Check it daily and keep it wet. In a day or so, your scallions will send up shoots of new life. There. Food for the asking. You can do this, grow your own herbs and vegetables if you have no green thumb, actually. Anything with a root, carrots, onions, radishes. Try to buy stuff with roots. They will keep on giving. Before long, you'll feel you have to cook something.
How about an omelette? Break two eggs in a bowl, add chopped scallions, chopped radishes, salt, pepper and some slivered cheese. Swirl with a fork as you wait for your skillet to get hot. Drop a pat of butter with a swirl of olive oil and shake the pan to coat the bottom. Drop your egg mixture and swirl this around so the bottom of your skillet is covered. Turn off the heat for two minutes and let the egg mixture cook without interference. Then, with a rubber spatula, fold the omelette and let it sit this way for a few minutes or while you make toast. Time required? Five minutes top.
The real trick is not to bother the eggs while they get golden at the bottom.
There. You have food for breakfast, lunch or dinner, or anytime, really. Your friends will be so amazed at the flavor you concocted and you didn't kill the plant. You just trimmed it a bit. In a few days, those strands of flavor will have grown by that window enough to invite you to scramble some more eggs.
Life couldn't be more generous!
