Beans are a fine tired-night food
Canned beans, rinsed and heated soft, can be dinner. Mash some if your child is still learning to chew.
Tired nights repeat a meal
Serve them with a food they already like. Tired nights are for repeating a meal, not inventing one.
Rinse the beans, warm them, and put a small amount beside rice or potato. That is a complete plan.
Texture
Whole beans can be a lot for a child still learning to chew. A mash, beside a few soft whole ones, lets them choose.
If they spit a piece out, stay calm and offer the familiar food. The beans can come back softer another day.
Not a special recipe
You do not need a new sauce. Salt and heat that suit a toddler are enough. Very hot food waits.
Beans can be the food they are learning, or the food they already accept. Either way, they are an ordinary dinner.
A sentence you can say
“Beans and the rice you like.”
