Chocolate Meal Replacement

I am currently in college and work part time at a restaurant. I am only able to eat before and after a shift and wanted to make a decent tasting liquid meal replacement with chocolate Metabolic Drive. I’m trying to gain weight, so carbs is a plus. I was hoping somebody who’s experimented with different mixes in a blender could give me some tips on different items to mix in to my shake to make a decent tasting meal replacement with around 500-600 calories. Thanks for your help.

I like Metabolic Drive Complete with real peanut butter or coconut oil. Throw in some fruit and you can easily hit you caloric needs.

1 cup chocolate calorie countdown
2 tbsp peanut butter
1 tbsp olive oil
30g pecans
2 scoops Metabolic Drive
1 serving greens product
