Add water, rice, salt, and ginger to the pot. Bring to a boil, and then reduce the heat. Cover with the lid and cook for about 25 minutes.
Drain the water from the tuna. Add the sesame oil and garlic to the tuna and mix well. Set aside.
Peel the cucumbers and steamed carrots. (Peeling makes them easier and safer for baby to eat.)
Chop into strips or a small dice. Strips are best for babies age 6 - 9 months, who use their whole hand to grab food. Babies older than about 9 months will start to learn how to grab diced veggies with their fingers.
Put some (or all) of the carrots into a microwave safe bowl and add two tablespoons of water. Microwave about 2 minutes, until the carrots are soft enough to smush with your fingers. (This makes them safe for baby.) Let the carrots cool.
Chop the green onions and slice the mango and avocado.
When the rice is done cooking, spoon the rice into two bowls.
Add the tuna, carrots, cucumbers, green onions, mango, and avocado.
Place small portions of each food on a plate or on baby’s highchair tray.
Optional: top the adult meals with sriracha, peanut oil, or seasoning (such as an “everything bagel” seasoning which contains sesame seeds and garlic)
