You need to make a "kitchen" somewhere else in your house so your toddler understands the designated eating area. Put together a corner with a little table, mini fridge, toaster oven, crockpot, and microwave. Eat lots of low prep meals- salads, paninis, slow cooker soups and stews, fruits and chopped veggies for the toddler, instant rice packets, sweet potatoes and other veggies steamed in the microwave, sausages in the toaster oven.
