Take a spoonful of shredded cheddar cheese and place as small round mounds on silpat or parchment paper. Keep adding additional spoons to make multiple small rounds until all 4 oz of cheese are used. Make sure they are placed apart as they will spread out as they melt.
Place in oven at 400°F for 8-10 minutes.
Remove from oven and let it cool for a few minutes.
Use a pizza cutter to slice each round into 2-3 pieces.
Cut 2 avocados and remove skin and seed and put in bowl. Mash with fork or masher.
