I will start the ball rolling. I usually have TWOMAD, a breakfast that is a fried English breakfast with toast and butter, and a grilled meat with potatoes and veg in the evening. I have been doing this for 7 years now since I started LCHF, and its a routine I have that suits me. But I have recently churned the energy consumption figures on how I do this, and it gave me a shock. This is something I repeat daily 365/annum so in a year and at present energy costs (pre October) my breakfasts cost me £90 p.a. and my evening meals cost £98 p.a just for the energy, My daily coffee cups cost me £200 p.a. because I use a kettle. This cost will almost dounble in the autumn.
So I looked at other ways I can reduce these costs. The obvious way is to migrate as much as I can to the microwave, which at 800W is quick and efficient. So far I have migrated my cups of coffee by just heating the mug of cold water for 2 mins and it makes a reasonable cup of coffee and its hot. I have successfully cooked my mushrooms at 2 mins in butter, Yep. So far so good. What I have not yet done is the bacon and the toast. The toast will remain being done in the toaster since that is better than the grill on the cooker. I await the arrival of the bacon crisper utensil for the microwave, but it should be possible to achieve a result. So yes my breakfast will transisition to the microwave, Cost will be around £20 pa, which is a saving of £70 at today;s prices.
Doing similar for the evening meal, I will be able to steam my pots and veg in the microwave, and I will try the meat crisper thingy for chops and burgers, but the fish will probably be steamed or poached instead of grilled. So its doable. Cost expected to reduce from £98 to £23 pa. My daily coffee habit reduces from £200 to £25 pa.
It will take a bit of getting used to, and involves a bit more utensil washing up but not too big a problem and I estimate to save around £300 pa off my bill today, and at least £600 pa from Jan 2023.
What I am not sure of transitioning is eggs (they can be poached or scrambled) or sausages or steaks. Salads don't fare well in a microwave either. But apparently stirfry and chicken is possible.
The oven will be needed at Christmas, and what I am doing may only be feasible as I am a household of one and the cat eats whatever I give him so long as its cold and smelly.
