Can I scramble up a bunch of eggs, and then freeze them in individual servings?
Not practically. The freeze-thaw process turns cooked eggs to rubber, and using any method to reheat them fry-pan, microwave, etc. is just going to make them worse.
We assume since scrambling eggs is one of the three easiest cooking processes (the others being boiling water and making toast) that you wish to prepare these in advance for someone who is not able to scramble eggs for him or herself. If this is the case, the person you're helping will be better fed with frozen muffins, tarts, breads, casseroles, soups, stews, etc., and will just have to look forward to your visits for a fresh batch of scrambled eggs.
