Just going to throw out that electric heaters are the most expensive/least efficient way to heat electrically.
If you’re in the US, you can get a partial credit for improving windows, doors, and insulation (always the best first step).
You or your landlord can also get up to a $3000 credit toward a central heat pump system, which gives 3-4x the delivered heat for a given amount of electricity.
I make as much as possible to avoid the flavor additives, texture modifiers, and preservatives found in much packaged food.
I make waffles from scratch and freeze them for quick breakfast. Prep large pots of soup, chili, stew, etc and freeze in deli tubs.
But as to who is right? No answer on that. I have built up plenty of cooking experience so things that seem tricky or time consuming to other people don’t faze me.
