1 can of tuna (flavour of your noitce, I like old school tuna in olive oil - hehe may not be the healthiest option)
1 can of 4 beans salad
a handful of corn (you can use the can variety; I go for fresh or frozen ones myself)
Cook the corn (if needed), rinse the beans, combine and presto!
It's not just good for you, it is yummo! And TLG likes it too so it's an easy toddler meal as well.
