It’s good that you’re looking to expand your food repertoire

If you’re dealing with arfid though you should consider a desensitization protocol to help deal with sensory or phobic response driving the arfid. What this looks like varies because it depends on what drives your arfid: is it a fear of aversive reaction, is it sensory, disinterest, etc.

That said building on what you have can be helpful. Changing the burritos slightly - change the protein, add a new vegetable, add guacamole, etc. try a new flavor of protein bar, etc.

If you’re looking for something in the healthy/low prep side of things I tend to make one big meal on sundays for the week and portion it out. It takes about 30-60 minutes depending on what I make. Japanese curry, various pastas, salads, soups, etc. how healthy these are varies. I am vegan so they tend to be a little bit better than the typical recipe you’d see online but some are still not the most healthy (Japanese curry for example is fairly high in fat but portioned correctly with rice is still filling and a reasonable amount of calories)
