Oatmeal. Not exactly date night, but it’s hot and healthy.
Get large flake oats, not the instant stuff.
Boil 1 cup of water in a small pot.
Decrease heat to mid-low.
Add 1/2 cup oats. Stir only once.
Cook for 10 minutes,
let cool for 10 minutes,
eat for 10 minutes.

You’ll want to watch it closely for a minute or two after you add the oats to make sure it doesn’t boil over. If it looks like its going to boil over just remove the pot from the heat till it calms down, and decrease the heat a little maybe, every oven is diff. It still needs to simmer though.

You can season it with whatever you want after cooking it: maple syrup, milk, oat milk, brown sugar, chocolate chips, raisins or other dried fruits (if you do raisins add them to the water before the oatmeal), cinammon, apples… etc.
Maybe a small pinch of salt.
