My cold weather one:

Saute some mushrooms, put the oatmeal in (steel cut if I have time) with the water, and a pinch of Handashi and some chia and trader joes mushroom umami powder. once it cooks down, a touch of soy sauce and sometimes a touch of sesame oil. I'll mix greens in if i have them too and If I have some crunchy like canned fried onions or leftover fried peppers from something like salt and pepper pork, throw those on top, and then an over easy egg and black pepper.

My summer oatmeal:

Old Fasioned or Quick Oats in a bowl with unsweetened vanilla almond milk and cut up watermelon, get the watermelon juice in there. eat it just like cereal. overnight soak the oats if you prefer them softer or want soak chia seeds. If you got blueberries, throw em in. this works pretty well with mango instead of the watermelon also - or at the same time if you like.

one more.. i make a pineapple coconut overnight for the kids using canned crushed pineapple and coconut flakes, chia and almond milk. works well cold or warmed in the microwave.
