Harriet - Its True I don't do oats.
There are buckwheat flakes sold, so I guess they would cook faster.
Its possible here to buy raw or roaster buckwheat - I'm guessing the buckwheat cooks faster.
Overnight soaking would help.
I would have said buckwheat had an 8-10 min cooking time, if you liked it chewy.
Mostly I put on water to heat after I take thyroid meds.
add my premixed seed mix of buckwheat and quinoa flakes, cashews and ground flaxseed . (I keep that in the fridge). (the flakes give it a porridge texture)
add chopped ginger and whatever fruit, and a little salt. ( chop up the ginger in slices and freeze, then chop up a slice when I start the mix cooking.)
By then my solid element has heated the water to almost a simmer. I turn the power off and walk away.
come back 30 - 60 min later from tmeds time.
Ratios I use for the mix in a 3 litre container that fits in the fridge door.
500g raw buckwheat
500g quinoa flakes
250 g/ cup ground flaxseed
Maybe a cup of cashews. that varies. Or I add some as I cook. (any allowed nut would do, or none)
My measuring cup I leave in the seed mix is an egg cup. 250ml water or more is possibly better.
I have 2 egg cups per serve which is huge, and takes me far into the day.
If you were also eating other things in the same meal, make less.
There is no reason why you couldn't put oats in there.
I mostly don't use the microwave.
I've heard people cast dispersions on them, as opposed to health giving qualities .
A good tablespoon /15ml of chia seed plus the flaxseed portion above is what I need atm for my feet to remain happy to be walked on.
If I haven't has the chia seed at lunch I'll add it to cook with rice and veg + whatever protein evening meal. It really bulks up that meal, or thickens a smoothy when left to swell 10 min or so.
I tried buckwheat or quinoa with evening meal but decided in the end I needed the carbs in the rice as part of my day/ night.
