Here in CathInfo, we've previously covered the details of abstinence, referring to authoritative sources, notably nearly 4 years ago, in a topic that spanned 2 Web pages:
"How Far Does Friday Abstinence Go?".

Rather than treading the same ground all over again in this newish topic, I recommend that newer CathInfo members simply read specific replies at these still-accessible links:

As is typical for CathInfo, the guidance and opinions expressed in original postings and replies are personal interpretations, altho' the 2 members above might have minds a bit more lawyerly than most other members.  On the other hand, I don't have the intellectual advantage of ever having been a student in a seminary (‘TKGS’ is welcome to offer his own disclaimer), but some members have indeed had that distinctive experience.

Machas a la Parmesana
 
For 2-4 people

Ingredients:
2 cans of Machas
3 slices of Havarti or Muenster cheese
2 tablespoons grated Parmesan cheese
1/4 cup of white wine
a trickle of heavy cream, optional
butter, optional
 
Preparation:
Preheat the oven broiler to maximum temperature.
Clean the Machas removing the bag with sand.
Put the Machas in a dish that can go to the oven, add the wine, salt, cream, butter in small pieces and pepper to taste. Cover with Havarti cheese and Parmesan cheese.
Broil in the oven until the cheese begins to brown. Take out carefully; it will be scorching and serve immediately with country bread.
