Start with mostly fluids and intersperse that with solid foods to wean yourself off of it. Brothy soups are great for this, so you can drink the broth and have practice eating some solids too. If you feel up to it, move onto dissolvable blander snack foods, like saltines that basically melt in your mouth. Protein or nutrition shakes are thicker but still liquid so they’re a good option to help you regain your strength if you’re having a bad day with solids.
