Reading through was hoping for more cooking theme instead of just healing stuff.
Maybe you need to add another theme to the cook idea.
Example: Cordon Bleu, The Exotic Chef (exotic = cannable)
Role: jungle / Fighter
Taste test(Passive): Enemies slain by Cordon's attacks or abilities drop "Morsels". Cordon can collect "Morsels" to heal himself for 2%. all "Morsels" last for 5 seconds. (5 second rule)
Chopping Block(Q) - Cordon uses his Butcher knife to cut a slice out of his enemies.
Cordon next auto-attack deals increased damage to a target. If the enemy unit is killed, the cooldown timer is reduced.
Enemy units killed this way, drop a "Morsels", Enemy champions will drop 2 X "Morsels"
Slice and Dice(W) - Toggle on: Cordon shreds enemies in front of him into tiny bits.
Cordon mows down enemy units in his path, he gains slight increase in movement speed and deals DOT each second. Enemies killed this way drop "Morsels"
Salt & pepper (E) - Cordon throws a bag of Spices towards his opponents, blinding and silencing them for 3 seconds.
Cooking Pot(R) - Cordon summons a large static cooking pot, with 1000HP at a target location for 10 seconds, The cooking pot emits a "Sizzling" aura that slows down enemies in the area, enemies in contact with Cordon are put into the pot and receive damage over time while inside. (up to 2 enemies champions). Enemies killed this way drop "Cooked Meat" and can be picked up allies and Cordon, and lasts 8 seconds. "Cooked meat" heals for 20% of Max HP, 10% Mana and have increased HP and resource regeneration for 4 seconds.
Enemies can destroy the Pot for early release.
I was tryng to avoid being like Tham Kench someone who eats stuff. so focused more on the cooking aspect.
My E is probably the weakest idea, but didn't know what else XD
