5 Healthy Dinner Recipes For When You're Eating Alone Tonight

Cooking for one is a weird kind of lonely. Every recipe serves four. Every ingredient comes in family-size. And the motivation to make a real meal just for yourself sits somewhere between low and nonexistent.

So you eat cereal. Or cheese and crackers. Or you stand over the sink eating cold leftovers like it doesn't count if you don't sit down.

But "just you" still deserves real food. These recipes are scaled for one person, use small amounts of ingredients so nothing rots in the fridge, and are actually worth the effort even when nobody is watching.

You matter enough to feed yourself properly.

Quick disclaimer: If you have specific dietary needs or health concerns, please consult with a healthcare provider.
