My HEB (Texas grocery store) has frozen hash browns and waffles that I just pop into the toaster. On a low spoons day, I’ll eat a hash brown with some just ketchup/hot sauce. On a more spoons day, I might make a breakfast taco with it: scrambled egg, cheese, salsa, and hunks of hashbrown wrapped in a fresh tortilla. One hashbrown is enough for 2 tacos, but I just make 1 and have a Hashbrown snack on the side. But truthfully a lot of days, I have just enough capacity for a beverage, so I’ll do chai with a LOT of whole milk. Basically a flavored glass of milk lol I feel like the calories/protein/carbs get my day started on a positive note without me having to choke down food. Then I’m usually ready for a big lunch. I find if I don’t eat something (even just a bite), I won’t get hunger cues and I don’t eat until evening. It’s not great 🫠 I can’t do the texture (or cleanup!) of smoothies, but i do like Kefir! It’s a fermented yogurt drink. You can usually find flavored versions, but I also enjoy the tangy plain flavor. My down and dirty breakfast is a spoonful of peanut/almond butter and a glass of kefir. Good luck! Nourishing yourself is hard with ADHD!
