Peanut butter toast.
Jam toast.
Cereals with oat milk.
Oatmeal and whatever your favorite seeds.
Mix and match.

I made my own blueberry jam the other day, and I don't think I'd ever buy it from the store again.
Blueberries, whatever sugar of your choice (I used a mix of maple syrup and raw sugar), I added a bit of sumac because I didn't have lemon on hand, heat until it foams, dump in a jar.
I had always put off making my own jam because in my mind, it meant I had to make a huge batch and deal with canning and everything, but in reality you can just make a small batch in 15 minutes, keep it in the fridge and make more whenever.
