I've just toasted some mixed nuts in the oven with butter, salt and worchester sauce for that salty-crunchy thang. Aprox. recipe: 2Tbs butter, 2 tsp worchester s., 1 cup each almonds, walnuts, hazelnuts, pecans, dash salt. Toast in 275 oven for 18 minutes, tossing every 9 or so. Better than nothing.
[reminds me of that great Chex Party Mix most of us miss very much]
A breakfast mainstay for me is a fruit smoothie: Half a banana, 1.5 cup frozen blueberries, raspb. etc, 1 tbs almond butter, 2-3 tbs yoghurt, water to help mix. Savage briefly in a blender.
[As William mentioned a limited number of banana might be tolerated to some extent, especially in this condition].
